Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, specifically to a safe unloading platform for construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. After the building materials required for construction are transported to the construction site, they need to be unloaded from the building material transport vehicles. Some building materials, such as stone, are heavy and require unloading platforms. However, the existing unloading platforms for construction are not convenient enough for unloading. The building materials need to be manually moved from the vehicle to the unloading platform, which affects the unloading efficiency. In addition, the building materials slide quickly on the sliding ramp during unloading and are easily damaged by bumps after falling. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a safe unloading platform for construction, which eliminates the need for manual unloading of building materials from vehicles, facilitates unloading, and improves unloading efficiency. The building materials are slowed down during the downward sliding process and are buffered and stopped after falling. Then, they are transferred to one side by a roller transfer mechanism, which can avoid damage to the building materials during the unloading process and effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a safe unloading platform for construction, comprising a base, wherein an unloading height adjustment mechanism is installed on the upper left side of the base, and further comprising: The lateral approach mechanism includes a longitudinal beam, guide rods, bending frames, connecting rods, supports, a lateral electro-hydraulic telescopic rod, and a telescopic plate. The top of the unloading height adjustment mechanism is fixedly connected to the longitudinal beam. The left ends of the front and rear ends of the longitudinal beam are respectively fixedly connected to the right ends of two transverse guide rods. The left ends of the two guide rods are respectively laterally slidably connected to the guide holes at the right ends of the horizontal parts of the two bending frames. The tops of the horizontal parts of the two bending frames are connected by a longitudinal connecting rod. The middle right side of the connecting rod is connected to the left end of the lateral electro-hydraulic telescopic rod. The right end of the lateral electro-hydraulic telescopic rod is fixedly connected to a support, which is fixed in the middle of the longitudinal beam. The right side of the vertical parts of the two bending frames is connected to the left end of the telescopic plate. The right end of the telescopic plate is connected to the top of the longitudinal beam. The telescopic plate is tilted with the left side higher than the right side. The building materials falling onto the telescopic plate will slide to the right along the upper side of the telescopic plate. The shovel-lifting and unloading mechanism is installed between the two curved frames; The unloading sliding guide mechanism is installed on the right side of the telescopic plate, and the right end of the unloading sliding guide mechanism is connected to the upper side of the base; the unloading sliding guide mechanism is equipped with an unloading deceleration mechanism in a rectangular array.

[0005] The base is placed next to the building material transport vehicle. Then, the unloading height adjustment mechanism controls the lifting and lowering of the lateral approach mechanism. The shovel unloading mechanism is aligned with the building materials on the transport vehicle. The support is used to install the lateral electric hydraulic telescopic rod. The extension of the lateral electric hydraulic telescopic rod can drive the bending frame to slide to the left along the guide rod, allowing the shovel unloading mechanism to approach the building materials on the transport vehicle. During the leftward sliding of the bending frame, the telescopic plate extends, and the shovel unloading mechanism scoops up the bottom of the building materials, allowing the building materials to slide onto the upper side of the telescopic plate. Then, it slides to the right along the upper side of the telescopic plate and falls onto the unloading sliding guide mechanism. During the rightward sliding on the unloading sliding guide mechanism, it is decelerated by the unloading deceleration mechanism and falls to the upper right end of the base, basically completing the unloading of building materials from the transport vehicle. The extension and retraction of the lateral electric hydraulic telescopic rod can change the left and right position of the shovel unloading mechanism, allowing it to scoop up building materials near the inside of the truck bed.

[0006] Furthermore, the telescopic plate includes a first support base, a hollow plate, a sliding plate, and a second support base. Two first support bases are fixedly connected to the right side of the vertical portions of the two curved frames, respectively. The two first support bases are movably connected to the front and rear sides of the left end of the hollow plate via a first movable shaft. The inner side of the right end of the hollow plate is slidably connected to the left end of the sliding plate. Two second support bases are fixedly connected to the front and rear sides of the top of the longitudinal beam, respectively. The two second support bases are movably connected to the front and rear sides of the right end of the sliding plate via a second movable shaft. The sliding plate slides inside the hollow plate, maintaining the ability of the upper part of the telescopic plate to slide through building materials during the left and right movement of the scooping and unloading mechanism while the telescopic electric hydraulic telescopic rod extends and retracts.

[0007] Furthermore, the shovel-lifting and unloading mechanism includes a rotating shaft, a shovel plate, support rods, and a push-pull control assembly. The tops of the vertical sections of the two curved frames are rotatably connected to the right end of the shovel plate via the rotating shaft. The left end of the shovel plate is thinner than the right end, and the left end of the shovel plate is the cutting edge. Two vertical support rods are fixedly connected to the bottom of the right end of the shovel plate, and the push-pull control assembly is connected to the bottom of the two support rods. When it is necessary to shovel building materials, the horizontally moving electro-hydraulic telescopic rod extends, pushing the left end of the shovel plate into the bottom of the building material. The push-pull control assembly pushes the support rod at the bottom of the right end of the shovel plate, causing the left end of the shovel plate to rotate around the rotating shaft, thereby lifting the left end of the shovel plate. The building material slides to the right along the upper side of the shovel plate, thus sliding onto the upper side of the telescopic plate.

[0008] Furthermore, the push-pull control assembly includes a universal ball seat 1, a universal ball 1, a push-pull rod, a universal ball seat 2, a longitudinal rod, a rotating sleeve, a fixed shaft, a crossbar, a control rod, a longitudinal electro-hydraulic telescopic rod, a movable seat, a movable shaft, and a universal ball 2. Two universal balls 1 are fixedly connected to the bottom right side of the two support rods. Each universal ball 1 contains a universal ball 1. Each universal ball 1 is fixedly connected to the left end of the push-pull rod. A universal ball 2 is fixedly connected to the right end of each push-pull rod. Each universal ball 2 is installed in conjunction with a universal ball seat 2. The front ends of the longitudinal rods are fixedly connected to the rear side of the ball seat two. The rear end of each longitudinal rod is fixedly connected to the top of the rotating sleeve. A fixed shaft is rotatably connected inside each rotating sleeve. A connecting rod is fixedly connected to the bottom end of the fixed shaft. The right end of the crossbar is fixedly connected to the bottom left side of each rotating sleeve. The left ends of the two crossbars are movably connected to the front and rear ends of the longitudinal control rod through the movable shaft three. The horizontal part of the front bending frame is movably connected to the front end of the longitudinal electro-hydraulic telescopic rod through the movable shaft. The rear end of the longitudinal electro-hydraulic telescopic rod is movably connected to the front end of the control rod through the movable shaft four. The longitudinal electro-hydraulic telescopic rod extends, thereby pushing the control rod to move backward. The control rod pushes the rotating sleeve to rotate clockwise around the fixed axis through the crossbar. The rotating sleeve drives the longitudinal rod and the universal ball seat two to rotate. Through the push-pull rod and the transmission of universal ball two and universal ball one at both ends, the support rod can be pushed to the left. The push rod can be pushed by the cooperation of universal ball two and universal ball seat two and universal ball one and universal ball seat one, and it is not affected by the angle. It can effectively push and pull the support rod. When the longitudinal electro-hydraulic telescopic rod shortens, the support rod can be pulled. At this time, the left end of the shovel plate moves downward.

[0009] Furthermore, the unloading sliding guide mechanism includes a support base three, a guide ramp, side protection components, and a sliding installation component. Two support bases three are fixedly connected to the right sides of the two support bases two respectively. The two support bases three are movably connected to the front and rear sides of the left end of the guide ramp via a movable shaft five. The right end of the guide ramp is connected to the front and rear ends of the upper side of the base via the sliding installation component. Side protection components are detachably installed on the front and rear sides of the upper surface of the guide ramp. The support base three is used to movably connect the left end of the guide ramp. During the lifting and lowering process of the unloading height adjustment mechanism, the guide ramp will move relative to the support base three. At this time, the right end of the guide ramp will also move relative to the base via the sliding installation component. The side protection components protect the front and rear sides of the upper surface of the guide ramp, preventing the building material from slipping off the front and rear sides of the guide ramp when sliding down the upper surface of the guide ramp, thus ensuring high safety.

[0010] Furthermore, the unloading deceleration mechanism includes a rectangular groove, a hinge support, a deceleration bend, a mounting rod, and a hydraulic buffer. The guide plate has four rectangular grooves arranged in a rectangular array. The bottom of the guide plate is fixedly connected to the hinge support at the left side of the rectangular groove. The hinge support is movably connected to the left end of the deceleration bend via a hinge shaft. The right end of the deceleration bend is bent upwards and extends through the rectangular groove to the upper side of the guide plate. The right end of the deceleration bend is arc-shaped. The bottom of the guide plate is fixedly connected to the mounting rod at the left side of the hinge support. The bottom end of the mounting rod is movably connected to one end of the hydraulic buffer via a mounting shaft. The other end of the hydraulic buffer is movably connected to the lower middle part of the deceleration bend via a mounting shaft. As the building material slides along the upper side of the guide ramp, it encounters the right end of the deceleration plate. The gravitational potential energy of the building material causes the deceleration plate to move relative to the hinge support around the hinge axis, compressing the hydraulic damper and causing it to shorten. When the deceleration plate retracts into the rectangular groove, the building material continues to slide along the guide ramp. This reduces the sliding speed of the building material, preventing it from sliding too fast on the guide ramp and falling to the ground and being damaged. This improves the safety of unloading the building material. After the building material slides past, the hydraulic damper returns to its original position and extends, pushing the right end of the deceleration plate back into the rectangular groove to wait for the next piece of building material to slide past.

[0011] Furthermore, the unloading deceleration mechanism also includes a failure control baffle and a retaining groove. The side of the guide ramp has a baffle groove communicating with the rectangular groove. The failure control baffle is slidably connected within the baffle groove. The side of the failure control baffle away from the rectangular groove has a retaining groove. If the building material is in block form and has high friction with the upper part of the guide ramp, and a deceleration bend in conjunction with a hydraulic buffer is not required for deceleration, the failure control baffle is inserted into the baffle groove, extending into the rectangular groove. The lower side of the failure control baffle abuts against the upper right end of the deceleration bend, preventing the deceleration bend from extending into the rectangular groove and thus preventing deceleration of the building material. The failure control baffle can be easily pulled out using the retaining groove.

[0012] Furthermore, it also includes a roller transfer mechanism, which comprises a transfer channel, a power channel, transverse transfer rollers, a power shaft, and a transfer power assembly. The upper surface of the base has a transfer channel on the right side, and a power channel is located on the left side of the transfer channel. Transverse transfer rollers are rotatably connected longitudinally at equal intervals within the transfer channel. The left end of each transverse transfer roller is fixedly connected to the right end of the power shaft, which extends into the power channel and connects to the transfer power assembly. After the building materials on the guide ramp slide down, they stop on the transverse transfer rollers. The transfer power assembly drives each transverse transfer roller to rotate via the power shaft. The rotating transverse transfer rollers convey the building materials backward, allowing them to leave the base and await the unloading of the next building material.

[0013] Furthermore, it also includes a buffer stopping mechanism, which comprises a buffer assembly, a disassembly assembly, a disassembly plate, and a buffer pad. The buffer assembly is installed on the right end of the upper surface of the base, and the disassembly plate is installed on the left side of the buffer assembly via the disassembly assembly. A buffer pad is provided on the left side of the disassembly plate. The buffer pad is made of rubber. When building materials on the guide ramp slip off at a high speed, they are likely to continue sliding to the right from the transverse transfer roller. The disassembly plate and the buffer pad stop the slipping building materials, providing the first level of buffer stopping. Then, the disassembly plate compresses the buffer assembly, allowing it to provide the second level of buffer stopping. The disassembly assembly allows the disassembly plate and the buffer pad to be removed and replaced, and different buffer pads can be used. With these two levels of buffer stopping, the slipping building materials can be safely stopped, preventing them from colliding and being damaged by other parts, thus ensuring high safety.

[0014] Furthermore, it also includes a base shifting control mechanism, which comprises casters and support locking components. Casters are installed at the four corners of the base's bottom, each caster equipped with a wheel brake. Support locking components are also installed at the four corners of the base. The casters allow for easy movement of the base to the desired position, and the wheel brakes lock the casters in place. The support locking components provide support and fixation for the base, ensuring its stability and preventing movement during unloading.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The horizontal electric hydraulic telescopic rod extends, pushing the left end of the shovel plate into the bottom of the building material. The push-pull control component pushes the support rod at the bottom right end of the shovel plate, causing the left end of the shovel plate to rotate around the pivot, thereby lifting the left end of the shovel plate. The building material slides to the right along the upper side of the shovel plate, thus sliding to the upper side of the telescopic plate, and then slides down along the guide ramp. There is no need for manual handling of building materials from the vehicle, making unloading convenient and improving unloading efficiency. 2. When the building material slides along the upper side of the guide ramp, it will encounter the right end of the deceleration plate. The gravitational potential energy of the building material will cause the deceleration plate to move relative to the hinge support with the hinge axis as the center. This will compress the hydraulic buffer and cause it to shorten. When the deceleration plate retracts into the rectangular groove, the building material continues to slide along the guide ramp. This can reduce the sliding speed of the building material and prevent it from sliding too fast on the guide ramp and falling to the ground and being damaged. This can improve the safety of unloading the building material. 3. After the building materials fall along the guide ramp, they will be stopped by the buffer stop mechanism and then transferred to one side by the roller transfer mechanism, which can prevent the building materials from being damaged by bumps during the unloading process.

Two vertical support rods 43 are fixedly connected to the bottom of the right end of the shovel plate 42, and the push-pull control assembly is connected to the bottom of the two support rods 43. When it is necessary to shovel building materials, the horizontally moving electric hydraulic telescopic rod 36 extends, pushing the left end of the shovel plate 42 to insert into the bottom of the building material. The push-pull control assembly pushes the support rods 43 at the bottom of the right end of the shovel plate 42, causing the left end of the shovel plate 42 to rotate around the rotating shaft 41, thereby lifting the left end of the shovel plate 42.

The longitudinal electro-hydraulic telescopic rod 413 extends, thereby pushing the control rod 412 to move backward. The control rod 412 pushes the rotating sleeve 49 to rotate clockwise around the fixed shaft 410 through the crossbar 411. The rotating sleeve 49 drives the longitudinal rod 48 and the universal ball seat 47 to rotate. Through the transmission of the push-pull rod 46 and the universal ball 416 and universal ball 45 at both ends, the support rod 43 can be pushed to the left.

The support base 3 51 is used to movably connect the left end of the guide ramp 52. During the lifting and lowering process of the unloading height adjustment mechanism 2, the guide ramp 52 will move relative to the support base 3 51. At this time, the right end of the guide ramp 52 will also move relative to the base 1 via the sliding installation component. The side protection components protect the front and rear sides of the upper surface of the guide ramp 52, preventing the building material from slipping off the front and rear sides of the guide ramp 52 when sliding down its upper surface, thus ensuring high safety.

[0023] The side protection assembly includes a snap-fit ​​groove 53, a side baffle 54, and a snap-fit ​​block 55. The upper surface of the guide ramp 52 is provided with two side baffles 54 on the front and rear sides respectively. Each side baffle 54 has snap-fit ​​blocks 55 at equal intervals at its bottom. The guide ramp 52 has a snap-fit ​​groove 53 at the position corresponding to the snap-fit ​​block 55. The snap-fit ​​block 55 snaps into the corresponding snap-fit ​​groove 53. The side baffle 54 is installed on the guide ramp 52 through the snap-fit ​​blocks 55 and snap-fit ​​grooves 53 that snap into each other. The side baffle 54 blocks the front and rear sides of the upper surface of the guide ramp 52 to prevent building materials from falling off the front and rear sides of the guide ramp 52 when sliding down the guide ramp 52.

The bottoms of the two support bases 4 56 are fixedly connected to the tops of the two dovetail sliders 57. The front and rear sides of the right end of the upper surface of the base 1 are respectively provided with two horizontal dovetail grooves 58. The upper surface of the base 1 is provided with two disassembly grooves 59 at the left ends of the two dovetail grooves 58. The two dovetail sliders 57 are slidably connected to the two dovetail grooves 58. The disassembly grooves 59 facilitate the installation of the dovetail sliders 57 into the dovetail grooves 58. As the unloading height adjustment mechanism 2 rises and falls, the right end of the guide ramp 52 slides left and right along the dovetail grooves 58 via the dovetail sliders 57.

[0025] The unloading deceleration mechanism 6 includes a rectangular groove 61, a hinge support 62, a deceleration bend 63, a mounting rod 64, and a hydraulic buffer 65.

The hinge support 62 is movably connected to the left end of the deceleration bend 63 through a hinge shaft. The right end of the deceleration bend 63 bends upward and extends through the rectangular groove 61 to the upper side of the guide plate 52. The right end of the deceleration bend 63 is arc-shaped. The bottom of the guide plate 52 is fixedly connected to the mounting rod 64 at the left side of the hinge support 62. The bottom end of the mounting rod 64 is movably connected to one end of the hydraulic buffer 65 through a mounting shaft 1. The other end of the hydraulic buffer 65 is movably connected to the lower middle part of the deceleration bend 63 through a mounting shaft 2. When the building material slides along the upper side of the guide ramp 52, it will encounter the right end of the deceleration plate 63. The gravitational potential energy of the building material will cause the deceleration plate 63 to move relative to the hinge support 62 with the hinge axis as the center, compressing the hydraulic buffer 65 and causing the hydraulic buffer 65 to shorten. When the deceleration plate 63 retracts into the rectangular groove 61, the building material continues to slide along the guide ramp 52. This can reduce the sliding speed of the building material and prevent it from sliding too fast on the guide ramp 52 and falling to the ground and being damaged. This can improve the safety of unloading the building material. After the building material slides past, the hydraulic buffer 65 returns to its original position and extends, pushing the right end of the deceleration plate 63 back into the rectangular groove 61 to wait for the next sliding building material to decelerate.

[0026] The unloading deceleration mechanism 6 also includes a failure control baffle 66 and a retaining groove 67. A baffle groove communicating with a rectangular groove 61 is provided on the side of the guide ramp 52. The failure control baffle 66 is slidably connected within the baffle groove. The retaining groove 67 is provided on the side of the failure control baffle 66 away from the rectangular groove 61. If the building material is in block form and has significant friction with the upper side of the guide ramp 52, and deceleration is not required with the deceleration bend 63 in conjunction with the hydraulic buffer 65, then the failure control baffle 66 is inserted into the baffle groove, extending into the rectangular groove 61. The lower side of the failure control baffle 66 abuts against the upper right end of the deceleration bend 63, preventing the deceleration bend 63 from extending into the rectangular groove 61 and thus preventing deceleration of the building material. The failure control baffle 66 can be easily pulled out using the retaining groove 67.

[0027] In use, the base 1 is placed next to the building material transport vehicle. Then, the unloading height adjustment mechanism 2 controls the lifting and lowering of the lateral approach mechanism 3, and the shovel unloading mechanism 4 is aligned with the building materials on the transport vehicle. The support 35 is used to install the lateral electric hydraulic telescopic rod 36. When the lateral electric hydraulic telescopic rod 36 extends, it can drive the bending frame 33 to slide to the left along the guide rod 32, allowing the shovel unloading mechanism 4 to approach the building materials on the transport vehicle. During the leftward sliding of the bending frame 33, the telescopic plate extends, aligning the shovel unloading mechanism 4 with the bottom of the building materials. The material is scooped up and slides onto the upper side of the telescopic plate. Then, it slides to the right along the upper side of the telescopic plate onto the unloading sliding guide mechanism 5. During the sliding to the right on the unloading sliding guide mechanism 5, it is decelerated by the unloading deceleration mechanism 6 and falls to the upper right end of the base 1, basically completing the unloading of the material from the material transport vehicle. The extension and retraction of the transverse electric hydraulic telescopic rod 36 can change the left and right position of the scooping and unloading mechanism 4, allowing the scooping and unloading mechanism 4 to scoop up the material near the inside of the vehicle compartment.

[0028] Example 2, please refer to Figures 1 to 12 This embodiment provides a technical solution: a safe unloading platform for construction. This embodiment is structurally similar to Embodiment 1, with the difference being: It also includes a roller transfer mechanism 7, which includes a transfer channel 71, a power channel 72, a transverse transfer roller 73, a power shaft 74, and a transfer power assembly. The transfer channel 71 is provided on the right side of the upper surface of the base 1, and the power channel 72 is provided on the upper surface of the base 1 at the position to the left of the transfer channel 71. The transverse transfer roller 73 is rotatably connected longitudinally at equal distances in the transfer channel 71. The left end of the transverse transfer roller 73 is fixedly connected to the right end of the power shaft 74, and the left end of the power shaft 74 extends into the power channel 72 and is connected to the transfer power assembly.

[0029] The transfer power assembly includes a sprocket 75, a chain 76, a driven gear 77, a driving gear 78, and a transfer motor 79. The left end of each power shaft 74 extends into the power channel 72 and is fixedly connected to a sprocket 75. Each sprocket 75 is connected by a chain 76. A driven gear 77 is fixedly connected to one of the power shafts 74. The transfer motor 79 is mounted on the base 1. The output shaft of the transfer motor 79 is fixedly connected to a driving gear 78. The driving gear 78 meshes with the driven gear 77. When the transfer motor 79 operates, it drives the power shaft 74 to rotate through the meshing action of the driving gear 78 and the driven gear 77. Through the transmission of the sprocket 75 and the chain 76, it drives all the power shafts 74 to rotate, thereby driving each horizontal transfer roller 73 to rotate in the same direction. The horizontal transfer rollers 73 rotating in the same direction can transport building materials forward or backward.

[0030] After the building materials on the guide plate 52 slide down, they stop on the transverse transfer rollers 73. The transfer power assembly drives each transverse transfer roller 73 to rotate through the power shaft 74. With the help of the rotating transverse transfer rollers 73, the building materials can be transported backward, allowing the building materials to leave the base 1 and wait for the unloading operation of the next building material.

[0031] Example 3, please refer to Figures 1 to 12 This embodiment provides a technical solution: a safe unloading platform for construction. This embodiment is structurally similar to Embodiment 2, with the difference being: It also includes a buffer stop mechanism 8, which includes a buffer assembly, a disassembly assembly, a disassembly plate 87 and a buffer pad 88. The buffer assembly is installed on the right end of the upper surface of the base 1. The disassembly plate 87 is installed on the left side of the buffer assembly through the disassembly assembly. The buffer pad 88 is provided on the left side of the disassembly plate 87.

[0032] The buffer assembly includes a fixed longitudinal plate 81, a hydraulic buffer 82, a supporting longitudinal plate 83, and a sliding rod 84. The fixed longitudinal plate 81 is fixedly connected to the right end of the upper surface of the base 1. The right ends of the two hydraulic buffers 82 are fixedly connected to the front and rear ends of the left side of the fixed longitudinal plate 81, respectively. The left ends of the two hydraulic buffers 82 are fixedly connected to the front and rear ends of the right side of the supporting longitudinal plate 83, respectively. The left end of the sliding rod 84 is fixedly connected to the right side of the middle part of the supporting longitudinal plate 83. The sliding rod 84 is laterally slidably connected to the sliding hole in the middle part of the fixed longitudinal plate 81. The disassembly assembly includes a support plate 85 and a disassembly clip 86. The support plate 85 is fixedly connected to the bottom left side of the supporting longitudinal plate 83. Two disassembly clips are opened on the left side of the supporting longitudinal plate 83. The two disassembly clips are respectively engaged with two disassembly clips 86. The left side of each of the two disassembly clips 86 is fixedly connected to the right side of the disassembly plate 87. The support plate 85 supports the bottom of the disassembly plate 87. The disassembly plate 87 and the buffer pad 88 can be detached and installed by means of the disassembly slot and disassembly strip 86. When the building material slides down and comes into contact with the buffer pad 88, the buffer pad 88 first buffers the impact. If the impact force is large, the hydraulic buffer 82 is compressed by the disassembly plate 87 and the support longitudinal plate 83. The hydraulic buffer 82 buffers the impact again, so that the sliding building material can stop smoothly and avoid damage to the sliding building material due to large impact force.

[0033] The buffer pad 88 is made of rubber. If the building material on the guide plate 52 slips off at a high speed, it may continue to slide to the right on the transverse transfer roller 73. The disassembly plate 87 and the buffer pad 88 are used to stop the slipping building material. The buffer pad 88 can play the first buffering and stopping function. Then, the disassembly plate 87 compresses the buffer assembly, allowing the buffer assembly to play the second buffering and stopping function. The disassembly assembly can disassemble and replace the disassembly plate 87 and the buffer pad 88. Different buffer pads 88 can be replaced. With the help of two buffering and stopping functions, the slipping building material can be safely stopped, avoiding collisions and damage to the building material and other parts, thus ensuring high safety.

[0034] Example 4, please refer to Figures 1 to 12 This embodiment provides a technical solution: a safe unloading platform for construction. This embodiment is structurally similar to Embodiment 3, with the difference being: It also includes a base shift control mechanism 9, which includes casters 91 and support locking components. Casters 91 are installed at the four corners of the bottom of the base 1, and each caster 91 is equipped with a wheel brake. Support locking components are installed at the four corners of the base 1.

[0035] The support locking assembly includes notches 92, a movable rod 93, a threaded sleeve 94, a threaded post 95, a handwheel 96, and a support plate 97. Notches 92 are formed at the four corners of the base 1. Each notch 92 is movably connected to one end of the movable rod 93 via an end shaft. The other end of the movable rod 93 is integrally connected to a threaded sleeve 94. A threaded post 95 is internally threaded into the threaded sleeve 94. A handwheel 96 is fixedly connected to the top of the threaded post 95. The support plate 97 is connected to the bottom of the threaded post 95. Anchor holes are formed on the support plate 97. The end shaft allows the movable rod 93 to move relative to the base 1, allowing the support plate 97 to align with a suitable position on the ground. The handwheel 96... The threaded column 95 is easy to rotate. The threaded action between the threaded column 95 and the threaded sleeve 94 allows it to move up and down relative to the threaded sleeve 94. The downward movement of the threaded column 95 relative to the threaded sleeve 94 allows the support plate 97 to contact the ground, increasing the contact area with the ground and making the base 1 more stable. If the base 1 is to be moved due to excessive impact from building materials, anchors can be inserted into the anchor holes on the support plate 97. The anchors are inserted into the ground to achieve strong fixation of the base 1. If it is necessary to move, the threaded column 95 is twisted to move upward relative to the threaded sleeve 94, allowing the support plate 97 to leave the ground. Then the wheel brake on the universal wheel 91 is released, and the universal wheel 91 is used to easily move the base 1.

[0036] The caster wheel 91 can easily move the base 1 to the desired position. Then, the caster wheel 91 can be locked and fixed by the wheel brake. The support locking component can support and fix the base 1, making the position of the base 1 more stable and preventing it from moving during unloading.

[0037] It is worth noting that the adjusting motor 23, the transverse electro-hydraulic telescopic rod 36, the longitudinal electro-hydraulic telescopic rod 413, and the transfer motor 79 disclosed in the above embodiments are all controlled by an external PLC controller, and the control method adopts the method commonly used in the prior art. The adjusting motor 23 and the transfer motor 79 are both servo motors that can rotate in both directions.
