Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering, in particular to a safety hoist for construction engineering. Background Art

[0002] In construction projects, a hoist is a mechanical device that meets the needs of vertical material transportation and lifting. It has a power system to provide power to drive the movement of related components, and uses devices such as drums and sprockets to drive wire ropes or chains to pull the material-carrying devices, and uses guide devices to ensure the accuracy and stability of vertical operation.

[0003] In some construction processes, the hoist needs to drive the materials to move to a higher height so that the operators at high places can pick them up and use them. When the materials move higher, the center of gravity of the hoist as a whole rises accordingly. In order to facilitate movement on site, the hoist is generally provided with outward wheels at the bottom, and the contact area with the ground is small. When the center of gravity rises, the stability is reduced. Some existing hoists do not have additional mechanisms to improve stability. When hit, the entire device may topple over, which will not only cause damage to the device and materials, but may even cause injury to the operators, and the safety is relatively low. Therefore, a safe hoist for construction projects is proposed to address the above problems. Summary of the invention

[0010] Preferably, one end of the connecting rod is slidably connected to the outer wall of the triangular block, and the other end of the connecting rod is fixedly connected to the outer wall of the wedge block.

[0011] Preferably, the limiting assembly comprises a clamping block, the clamping block is elastically connected to the inner wall of the baffle through a return spring, a concave rod is slidably connected to the inner wall of the baffle, and a clamping groove is provided on the inner wall of the placement box.

[0012] Preferably, the block is slidably connected to the inner wall of the baffle, one end of the return spring is fixedly connected to the inner wall of the baffle, the other end of the return spring is fixedly connected to the outer wall of the block, the block is engaged with the slot, and the concave rod is fixedly connected to the outer wall of the block.

[0013] Preferably, the buffer mechanism comprises a sleeve rod, the inner wall of which is provided with a groove, the inner wall of which is slidably connected to an inner rod, the bottom outer wall of the inner rod is fixedly connected to a rubber pad, and the top outer wall of the base is elastically connected to a partition via a buffer spring.

[0014] Preferably, the sleeve rod is fixedly connected to the top outer wall of the base, the inner rod is fixedly connected to the bottom outer wall of the partition, and the partition is slidably connected to the inner wall of the fixed plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention cooperates with structures such as a moving block and a bottom plate. When an operator pulls the placement box upward through a driving assembly, the moving block drives the connecting block to move upward, and the gear drives the rack B to move downward. The bottom plate moves synchronously and contacts the ground, thereby increasing the contact area with the ground, so as to avoid the poor stability of the device due to the excessively high center of gravity when the placement box and the material are raised, thereby avoiding the problem of the device tipping over and causing damage to personnel or equipment. The present invention does not require an operator to intervene and operate, and the stability can be automatically improved during the placement box lifting process, which is more convenient.

[0018] The present invention cooperates with structures such as a card block and a concave rod, and by pressing the convex block at the front end of the concave rod, two groups of card blocks can be driven to move toward the inside of the baffle at the same time, and the baffle can be released from contact with the card slot to move it up and down, and adjusted according to the height of the material. The baffle can be fixed by the card block and the card slot, so that the overall height of the placement box does not need to be adjusted by turning the bolts multiple times, thereby facilitating the adjustment process.

[0019] The present invention cooperates with structures such as buffer springs and rubber pads. When the placement box falls unexpectedly, the partition and the buffer spring can play a buffering effect. The rubber pads are constantly in contact with multiple groups of slide grooves, which can increase the friction when the partition moves, reduce the amplitude of vibration, and convert the rigid impact of the placement box into a flexible impact, thereby reducing the damage to the materials inside the placement box when it falls.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, the present invention provides a construction engineering safety hoist, comprising a base 1, a fixing plate 2 is fixedly connected to the top outer wall of the base 1, a partition 9 is provided on the top outer wall of the base 1 through a buffer mechanism 8, a baffle 5 is provided on the top outer wall of the fixing plate 2 through a driving assembly 6, a placement box 4 is provided on the outer wall of the baffle 5 through a limiting assembly, and a stabilizing mechanism 3 is provided on the top outer wall of the base 1; the stabilizing mechanism 3 comprises a shroud 301, a rotating shaft 302 is rotatably connected to the inner wall of the shroud 301, a gear 303 is fixedly connected to the outer wall of the rotating shaft 302, a moving block 304 is fixedly connected to the outer wall of the placement box 4, and the bottom The top outer wall of the seat 1 is fixedly connected to a fixing rod 310, the outer wall of the fixing rod 310 is slidably connected to a connecting block 305, the inner wall of the connecting block 305 is elastically connected to a wedge block 313 via a connecting spring 312, the inner wall of the connecting block 305 is slidably connected to a connecting rod 314, the top outer wall of the fixing rod 310 is fixedly connected to a triangular block 311, the outer wall of the connecting block 305 is fixedly connected to a rack A306, the inner wall of the base 1 is slidably connected to a moving rod 307, the top outer wall of the moving rod 307 is fixedly connected to a rack B308, and the bottom outer wall of the moving rod 307 is fixedly connected to a bottom plate 309.

[0031] The above scheme is adopted: a universal wheel is arranged at the bottom of the base 1, and the device can be pushed to the working place by the universal wheel. When in use, the universal wheel can be locked to fix the device. The driving component 6 at the top is provided with a motor and a traction rope. When the output shaft of the motor rotates, it can drive the drum with the traction rope to rotate, so that the traction rope generates a pulling force on the baffle 5 and the placement box 4, and the baffle 5 and the placement box 4 are lifted upward, thereby lifting the material in the placement box 4, which is the prior art; through the setting of the buffer mechanism 8 below, when the traction rope breaks, the placement box 4 falls on the partition 9, and the buffer mechanism 8 absorbs the impact force to prevent the placement box 4 from falling and affecting the internal materials, reduce the impact force when falling, and provide a better buffering effect; through the setting of the limit component, the height of the baffle 5 in the placement box 4 can be adjusted to adapt to materials of different heights, and the materials can be blocked to prevent the materials from being too high during the lifting process and falling from the placement box 4.

[0032] By starting the motor, the traction rope can pull the baffle 5 and the placement box 4 upwards. During the movement, the stabilizing mechanism 3 can be driven to move the bottom plate 309 downwards to contact the ground, thereby increasing the contact area with the ground and improving stability, thereby avoiding the problem of unstable center of gravity caused by excessive material rise, which may cause the entire device to tip over. When not affected by external forces, the bottom end of the placement box 4 contacts the top outer wall of the partition 9. At this time, the bottom tooth block of the rack A306 is meshed with the gear 303, thereby making the top tooth block of the rack B308 mesh with the gear 303. When the placement box 4 is pulled upwards, the moving block 304 moves accordingly, thereby driving the connecting block 305 and the rack A306 to move upwards, driving the gear 303 to rotate, thereby driving the rack B308 to move downwards, and making the connecting rod 314 move synchronously, thereby driving the bottom plate 309 to move downwards to contact the ground, thereby increasing the contact area and making the device more stable.

[0033] like Figures 2 to 5 As shown, the enclosure 301 is fixedly connected to the top outer wall of the base 1, and the gear 303 is meshed with the rack A306 and the rack B308; the moving block 304 is slidably connected to the inner wall of the fixed plate 2, and the triangular block 311 is slidably connected to the inner wall of the connecting block 305; one end of the connecting spring 312 is fixedly connected to the outer wall of the wedge block 313, and the other end of the connecting spring 312 is fixedly connected to the inner wall of the connecting block 305, the outer wall of the wedge block 313 is slidably connected to the inner wall of the connecting block 305, and the wedge block 313 is clamped with the inner wall of the moving block 304; one end of the connecting rod 314 is slidably connected to the outer wall of the triangular block 311, and the other end of the connecting rod 314 is fixedly connected to the outer wall of the wedge block 313.

[0034] The above scheme is adopted: one end of the rotating shaft 302 is rotatably connected to the inner wall of the enclosure 301, and the other end is rotatably connected to the outer wall of the fixed plate 2. After the operator places the material in the placement box 4, the placement box 4 and the baffle 5 are pulled upward by the driving component 6, and the moving block 304 moves accordingly. In this state, the wedge block 313 is engaged with the inner wall limit groove of the moving block 304. When the moving block 304 moves upward, it will drive the wedge block 313 to move upward synchronously, and drive the connecting block 305 to move upward, while the fixed rod 310 and the triangular block 311 are in a fixed state. When the wedge block 313 and the connecting block 305 move upward, the connecting rod 314 moves along the bottom end of the inclined surface of the triangular block 311 to the top end, and moves laterally along the inclined surface toward the inner wall of the connecting block 305, driving the wedge block 313 to move laterally synchronously, so that the wedge block 313 moves upward and laterally toward the inner wall of the connecting block 305, and gradually loses contact with the limiting groove on the inner wall of the moving block 304; when the connecting block 305 moves upward, the rack A306 meshes with the gear 303, causing the gear 303 to rotate, and drives the rack B308 to move downward through the gear 303, driving the moving rod 307 and the bottom plate 309 to move downward, so that the bottom plate 309 contacts the ground, thereby improving stability.

[0035] When the bottom plate 309 is in contact with the ground, the wedge block 313 is completely out of contact with the limiting groove on the inner wall of the moving block 304. Since the bottom plate 309 is heavier, the position of the moving rod 307, the rack B308 and the gear 303 is fixed, so that the position of the rack A306 and the connecting block 305 is fixed, and it will not continue to move upward with the placement box 4 and the moving block 304; and when the driving component 6 moves the placement box 4 downward, the moving block 304 contacts the top of the connecting block 305 and moves downward along the outer wall of the connecting block 305, squeezing the arc surface of the wedge block 313, and the wedge block 313 moves inward along the inner wall of the connecting block 305, and the connecting spring 312 is forced to shrink; the downward pressure of the moving block 304 on the wedge block 313 is less than the gravity of the bottom plate 309, so that the connecting block 305 will not move downward during the downward pressing process, and the wedge block 313 will only be squeezed to make it When the movable block 304 moves to the point where its inner wall contacts the outer wall at the top of the connecting block 305 and continues to move downward, the elastic force of the connecting spring 312 causes the wedge block 313 to pop out and engage with the inner wall limit groove of the movable block 304. The inner wall of the movable block 304 exerts a greater pressure on the outer wall at the top of the connecting block 305, which can then exert a greater pressure on the connecting block 305, causing the connecting block 305 to move downward, and the gear 303 is driven to rotate by the rack A 306. The gear 303 causes the rack B 308 to move upward, driving the movable rod 307 and the bottom plate 309 to move upward and out of contact with the ground, thereby releasing the effect of improving the stability of the device and moving the device. This not only makes the device more stable, but also does not require the operator to intervene and perform additional operations. When the placement box 4 is lifted upward for feeding, the stability can be automatically improved, which is more convenient.

[0036] like Figure 6 As shown, the limiting assembly includes a clamping block 702, which is elastically connected to the inner wall of the baffle 5 through a reset spring 701, and the inner wall of the baffle 5 is slidably connected with a concave rod 703, and the inner wall of the placement box 4 is provided with a clamping groove 704; the clamping block 702 is slidably connected to the inner wall of the baffle 5, one end of the reset spring 701 is fixedly connected to the inner wall of the baffle 5, and the other end of the reset spring 701 is fixedly connected to the outer wall of the clamping block 702, the clamping block 702 is clamped with the clamping groove 704, and the concave rod 703 is fixedly connected to the outer wall of the clamping block 702.

[0037] By adopting the above scheme: the baffle 5 can move up and down in the inner wall of the placement box 4, so that materials of different heights can be placed, and the two sides of the higher materials can be blocked to prevent them from falling; when not affected by external forces, the blocks 702 in the inner walls on both sides of the baffle 5 are ejected due to the elastic force of the return spring 701 and are engaged with a group of card slots 704, so that the baffle 5 and the placement box 4 can be fixed; the two ends of the concave rod 703 are respectively fixedly connected with the two groups of card blocks 702, and the top of the concave rod 703 is provided with a convex block, which passes through the front end outer wall of the baffle 5, pressing When the protrusion is turned, the concave rod 703 and the two groups of blocks 702 can be driven to move inward synchronously, and engage with a group of slots 704, thereby releasing the limit of the baffle 5 and moving the baffle 5 up and down; and there are multiple groups of slots 704, and when the baffle 5 moves to a suitable position, the block 702 is positioned relative to the corresponding group of slots 704. At this time, the protrusion is released, and under the elastic force of the return spring 701, the block 702 pops out and engages with the corresponding slot 704, completing the adjustment of the baffle 5. It is relatively convenient and quick, and there is no need to operate by turning the bolts multiple times, saving time and effort.

[0038] like Figure 7 and Figure 8 As shown, the buffer mechanism 8 includes a sleeve rod 801, the inner wall of which is provided with a groove 802, the inner wall of the sleeve rod 801 is slidably connected with an inner rod 804, the bottom outer wall of the inner rod 804 is fixedly connected with a rubber pad 805, and the top outer wall of the base 1 is elastically connected with a partition 9 through a buffer spring 803; the sleeve rod 801 is fixedly connected to the top outer wall of the base 1, the inner rod 804 is fixedly connected to the bottom outer wall of the partition 9, and the partition 9 is slidably connected to the inner wall of the fixed plate 2; one end of the buffer spring 803 is fixedly connected to the top outer wall of the base 1, and the other end of the buffer spring 803 is fixedly connected to the bottom outer wall of the partition 9, and the rubber pad 805 contacts the inner wall of the groove 802.

[0039] The above scheme is adopted: through the buffer mechanism 8, a good buffering effect can be achieved when the placement box 4 falls unexpectedly, so as to prevent the internal materials from being damaged by excessive impact; when the placement box 4 falls onto the partition 9, the partition 9 moves downward, the buffer spring 803 is forced to shrink, and the inner rod 804 moves downward along the inner wall of the sleeve rod 801. During the movement, the rubber pad 805 continuously contacts the inner walls of the multiple groups of grooves 802, and is squeezed and deformed by the inner walls of the grooves 802, thereby increasing the friction force when the inner rod 804 moves, reducing the amplitude of the movement of the partition 9, thereby further improving the buffering effect, and converting the rigid impact of the placement box 4 when it falls into a flexible impact, thereby reducing the impact damage to the internal materials, and achieving a certain protective effect; and through the elastic force of the buffer spring 803 itself, the partition 9 can be moved upward and reset, the rubber pad 805 contacts the inner wall of the groove 802, and the inner rod 804 moves upward along the inner wall of the sleeve rod 801, and can be restored to the initial state.

[0040] The working principle and use process of the present invention:

[0041] Through the universal wheels provided under the base 1, the operator can push the device to the place to be used, and pull the traction rope through the motor in the driving assembly 6, so that it can pull up the placement box 4 and the baffle 5 and move them upward. At this time, the moving block 304 on the outer wall of the placement box 4 moves accordingly, driving the connecting block 305 and the rack A306 to move upward. Since the wedge block 313 is engaged with the limiting groove on the inner wall of the moving block 304, the upward movement of the moving block 304 will drive the wedge block 313 to move upward synchronously, and make the connecting block 305 move synchronously. Since the fixed rod 310 and the triangular block 311 are in a fixed state, the connecting rod 314 moves along the bottom end of the inclined surface of the triangular block 311 to the top end, and moves laterally along the inclined surface toward the inner wall of the connecting block 305, driving the wedge block 313 to move laterally into the inner wall of the connecting block 305, and gradually disengage from the limiting groove on the inner wall of the moving block 304.

[0042] When the connecting block 305 moves upward, the rack A306 meshes with the gear 303 to rotate the gear 303, and the gear 303 drives the rack B308 to move downward, driving the moving rod 307 and the bottom plate 309 to move downward, so that the bottom plate 309 contacts the ground, increasing the contact area with the ground, thereby improving the stability of the device and preventing the material from being lifted too high and causing the center of gravity to be unstable and tipping over.

[0043] When the driving assembly 6 moves the placement box 4 downward, the moving block 304 contacts the top of the connecting block 305 and moves downward along the outer wall of the connecting block 305, squeezing the arc surface of the wedge block 313, and the wedge block 313 moves inward along the inner wall of the connecting block 305, and the connecting spring 312 is forced to shrink; when the moving block 304 moves until its inner wall contacts the outer wall of the top of the connecting block 305 and continues to move downward, the elastic force of the connecting spring 312 causes the wedge block 313 to pop out and engage with the inner wall limit groove of the moving block 304. At this time, the inner wall of the moving block 304 is against the connecting The outer wall at the top of the connecting block 305 generates a large pressure, which causes the connecting block 305 to move downward. The connecting block 305 drives the gear 303 to rotate through the rack A306. The gear 303 causes the rack B308 to move upward, driving the moving rod 307 and the bottom plate 309 to move upward and break contact with the ground, thereby releasing the stabilizing effect of the device and moving the device. This not only improves the stability of the device, but also does not require an operator to intervene when moving the bottom plate 309. The movement of the bottom plate 309 can be automatically completed by moving the placement box 4 upward, which is more convenient.

[0044] The baffle 5 can move up and down in the inner wall of the placement box 4 to block materials at different heights and prevent the materials from falling from the placement box 4 during the lifting process; the operator can press the protrusion to drive the concave rod 703 and the two groups of blocks 702 to move inward synchronously, disengage from the slot 704, and release the limit of the baffle 5. At this time, the baffle 5 can be moved up and down according to the height of the material to adjust the combined height between the placement box 4 and the baffle 5; when the baffle 5 moves to a suitable position, the block 702 is opposite to a group of slots 704. At this time, the protrusion is released, and the block 702 pops out and engages with the corresponding slot 704 under the elastic force of the reset spring 701, completing the adjustment of the baffle 5. There is no need to adjust by turning multiple groups of bolts one by one, and the operation is more convenient and quick.

[0045] When the traction rope in the driving assembly 6 breaks, or other unexpected circumstances cause the placement box 4 to fall onto the partition 9, the partition 9 moves downward, the buffer spring 803 is forced to shrink, and at the same time the inner rod 804 moves downward along the inner wall of the sleeve rod 801. The rubber pad 805 at the bottom end of the inner rod 804 continuously contacts the multiple groups of grooves 802 on the inner wall of the sleeve rod 801 during the movement, and is squeezed by the inner wall of the groove 802 to produce deformation, thereby increasing the friction force when the inner rod 804 moves and reducing the movement amplitude of the partition 9; the partition 9 can be moved upward and reset by the elastic force of the buffer spring 803 itself, the rubber pad 805 contacts the inner wall of the groove 802, and the inner rod 804 moves upward along the inner wall of the sleeve rod 801, so that the buffer mechanism 8 is restored to its initial state; thereby, through the joint action of the buffer spring 803 and the rubber pad 805, the rigid impact when the placement box 4 falls is converted into a flexible impact, thereby reducing the impact damage to the material inside the placement box 4.
