Description

Technical Field

[0001] The present invention belongs to the technical field of housing construction protection, and specifically refers to a protection device for housing construction. Background Art

[0002] Housing construction projects generally refer to various technical works such as surveying, planning, design, construction, installation, and maintenance for newly building, rebuilding, or expanding housing buildings and ancillary structures, as well as the completed engineering entities. Specifically, housing construction means building houses and other buildings on the land where infrastructure construction has been completed. When carrying out housing construction, in order to protect construction safety, a protection device needs to be arranged around the building.

[0003] In the prior art, a surrounding protection structure is jointly formed by splicing multiple groups of fences. However, the existing protection devices often adopt a baffle with an integral structure, which is relatively large in overall structure, difficult to adjust the protection range, inconvenient for disassembly, installation, and transportation, and the pushable protection devices are difficult to ensure stability during use, and it is impossible to achieve a balance between convenient disassembly and stability; in addition, the existing protection devices are difficult to increase the stability of the device while being impacted, easily causing the protection device to tip over and personnel to be injured. Summary of the Invention

[0004] To solve the above-mentioned existing problems, the present invention provides a protection device for housing construction that is convenient for adjusting the protection range, ensures stability while being convenient for disassembly, installation, and transportation. In addition, by utilizing the characteristics of elastic materials combined with the hydraulic principle, when being impacted by the outside world, the coverage range of the counterweight blocks for supporting the non-force-bearing surface is increased, avoiding the device from tipping inward under the impact and causing personnel injuries.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows: A protection device for housing construction provided by the present invention includes a support housing. Inside the support housing, there is a stepping and lifting support assembly. An extended protection enclosure assembly is arranged on the stepping and lifting support assembly. A spring-acting anti-collision assembly is arranged on the front side of the support housing and the extended protection enclosure assembly. Among them, the stepping and lifting support assembly includes a first bidirectional telescopic rod, a connecting plate, a bidirectional threaded rod, and a stepping mechanism. The first bidirectional telescopic rods are symmetrically arranged up and down. The first bidirectional telescopic rods are horizontally arranged inside the support housing and slide up and down inside the support housing. The first bidirectional telescopic rod is a three-section telescopic rod. The connecting plates are symmetrically connected to the middle parts of the first bidirectional telescopic rods front and back. The bidirectional threaded rod is vertically rotatably connected between the first bidirectional telescopic rods. The bidirectional threaded rod is arranged inside the symmetric connecting plates. The stepping mechanism is arranged below the first bidirectional telescopic rods;

[0006] Furthermore, the extended protective fence assembly includes a telescopic expansion mechanism, an extended protection mechanism, and a connection mechanism. The telescopic expansion mechanism is arranged on the bidirectional threaded rod. The extended protection mechanisms are symmetrically arranged on both sides of the telescopic expansion mechanism. The symmetric extended protection mechanisms are respectively connected to the output ends on both sides of the first bidirectional telescopic rod. The connection mechanism is arranged on the extended protection mechanism.

[0007] Furthermore, the lower end of the support housing is open at both sides. A support plate is connected to the lower part of the inner wall of the support housing. Universal wheels are evenly arranged at the lower part of the support plate. An activity groove penetrates through the middle of the support plate. Pressing grooves penetrate through both sides of the activity groove and are symmetrically arranged on the support plate. The pressing grooves are arranged between the universal wheels. Yielding notch openings and guiding grooves penetrate through the rear side wall of the support housing respectively. The yielding notch opening is arranged directly above the guiding groove. The guiding groove is in a vertical semi-circular arc shape. A clamping groove is connected to the lower end of the guiding groove and extends upward.

[0008] Preferably, pressing rods are symmetrically arranged on the lower wall of the lower first bidirectional telescopic rod. The pressing rods penetrate and slide in the pressing grooves. A pressing cylinder is arranged at the lower end of the pressing rod. The pressing cylinder is in a waist shape and covers the upper parts of two universal wheels on the same side. A rubber pad is arranged around the inner side of the pressing cylinder. The arrangement of the universal wheels facilitates the movement of the device. However, when the pressing cylinder is pressed down, the pressing cylinder presses on the universal wheels. The rubber pad on its inner side contacts and squeezes the universal wheels. Under the restriction of the friction force of the rubber pad, the universal wheels are difficult to rotate and only provide support force, improving the stability of the device.

[0009] The thread directions at both ends of the bidirectional threaded rod are opposite. A screw tooth is arranged in the middle of the outer wall of the bidirectional threaded rod. An adjusting knob is rotatably arranged on one side of the connecting plate. The adjusting knob penetrates through the support housing and is movably arranged in the yielding notch opening. An adjusting wheel is arranged at the end of the adjusting knob penetrating through the connecting plate. The adjusting wheel meshes with the screw tooth.

[0010] Furthermore, the stepping mechanism includes a rotating column, a lifting block, a rotating rod, and a clamping rod. The rotating column is rotatably arranged inside the support housing. The rotating column is arranged below the lower first bidirectional telescopic rod. The lifting block is arranged on the rotating column. The lifting block is in a fan-shaped column shape and is movably arranged in the activity groove. The rotating rod is arranged at one end of the rotating column close to the adjusting knob and extends toward the side of the rotating column away from the lifting block. The rotating rod rotates inside the support housing. The clamping rod is movably arranged inside the end of the rotating rod away from the lifting block. A clamping spring is connected between the clamping rod and the rotating rod. The clamping rod moves in the guiding groove and the clamping groove. A pedal is rotatably arranged at the end of the clamping rod. When the clamping rod is at the lowest end of the guiding groove, the clamping rod springs into the clamping groove under the elastic action of the clamping spring, preventing the rotating rod from rotating under external force.

[0011] Further, the telescopic expansion mechanism includes an adjustment block, a first cross bar, a transition bar, a transition block, and a second cross bar. The adjustment blocks are symmetrically and movably arranged at both ends of the bidirectional threaded rod. The adjustment blocks are meshingly sleeved on the bidirectional threaded rod. The transition bars are symmetrically arranged on both sides of the bidirectional threaded rod and are connected to the second-stage telescopic ends of the symmetric first bidirectional telescopic rods. The transition bars are symmetrically arranged on both sides of the bidirectional threaded rod. The transition blocks are symmetrically slidably sleeved on the transition bars. Multiple groups of the first cross bars are respectively rotatably connected between the adjustment block and the transition block far from the adjustment block. The first cross bars are symmetrically arranged on both sides of the adjustment block. Two of the first cross bars on the same side are cross-rotatably connected to each other. The rotation connection shaft of the first cross bar is slidably arranged up and down in the support housing. One end of the first cross bar close to the adjustment block is provided with a telescopic structure. Multiple groups of the second cross bars are respectively rotatably arranged on the side of the transition block far from the first cross bar. The ends of the second cross bars that are symmetrically arranged up and down and far from the transition block are rotatably connected.

[0012] Further, the extended protection mechanism includes side blocks, counterweight blocks, and extension plates. The side blocks are symmetrically connected to the telescopic ends of the first bidirectional telescopic rods. The rotation connection shaft of the second cross bar is arranged in the side block. The counterweight block is arranged at the lower part of the side block. The interiors of the side block and the counterweight block are hollow and communicate with each other. A convex plate is provided on one side of the upper wall of the side block far from the adjustment knob. A liquid inlet hole is provided through the upper wall of the side block. A liquid outlet plug is provided on the side of the counterweight block far from the pressing cylinder.

[0013] During use, according to site restrictions or construction requirements, rotate the adjustment knob. The adjustment wheel meshes with the screw teeth. By rotating the adjustment knob, the bidirectional threaded rod is driven to rotate. The rotating bidirectional threaded rod drives the adjustment blocks meshing with its two ends to move towards or away from each other. When the symmetric adjustment blocks move towards each other, one end of the first cross bar connected to them follows the adjustment blocks to move towards each other. Under the restriction of the cross-rotation axis of the first cross bar, the end of the first cross bar close to the adjustment block adaptively expands and contracts. According to the lever principle and the Pythagorean theorem, the end of the first cross bar connected to the transition block also moves towards each other. Furthermore, while the transition block slides on the transition bar, it pushes the transition bar to move outward, thereby driving the end of the second cross bar connected to the transition block to move towards each other, and then pushing the side block to expand and move outward. The first bidirectional telescopic rod with a three-stage telescopic structure adaptively extends according to the moving distances of the transition bar and the side block, thereby expanding the overall width of the device and increasing the protection range. Similarly, when the symmetric adjustment blocks move away from each other, the symmetric side blocks contract and move inward under the drive of the first cross bar and the second cross bar, thereby reducing the protection range, and the adjustment is convenient.

[0014] Further, an extrusion groove is vertically provided at the connection between the counterweight block and the outer wall of the side baffle block. A pushing groove is horizontally provided inside the bottom wall of the counterweight block. The extrusion groove is communicated with the pushing groove. The pushing groove penetrates through the side wall of the counterweight block away from the extrusion groove. The extension plate is slidably arranged in the pushing groove;

[0015] Further, the elastic anti-collision assembly includes a fixed connecting rod, a second bidirectional telescopic rod, a movable connecting rod, a follower connecting rod, an elastic bent plate and a bidirectional telescopic connecting plate. The fixed connecting rod is arranged at the upper end of the side wall of the support housing away from the adjusting grip. The second bidirectional telescopic rod is slidably arranged on the side wall of the support housing. The second bidirectional telescopic rod is horizontally arranged below the fixed connecting rod. A return plate is arranged on the side wall of the support housing. The return plate is arranged below the second bidirectional telescopic rod. A plurality of return springs are evenly connected between the second bidirectional telescopic rod and the return plate. The movable connecting rod and the follower connecting rod are respectively slidably arranged on the side wall of the side baffle block close to the convex plate. The movable connecting rod slides on the convex plate. The follower connecting rod is symmetrically arranged at the output end of the second bidirectional telescopic rod. A plurality of groups of elastic bent plates are respectively evenly connected between the fixed connecting rod and the second bidirectional telescopic rod and between the movable connecting rod and the follower connecting rod. The elastic bent plates protrude outwards in an arc shape. The elastic bent plates are made of a high-elastic composite material. The bidirectional telescopic connecting plate is connected to the middle of the elastic bent plate between the fixed connecting rod and the second bidirectional telescopic rod. Follower plates are respectively arranged at the output ends on both sides of the bidirectional telescopic connecting plate. The follower plates are connected to the middle of the elastic bent plate between the movable connecting rod and the follower connecting rod. The second bidirectional telescopic rod and the bidirectional telescopic connecting plate are of a three-stage telescopic structure.

[0016] Further, an extrusion plug plate is vertically provided at the lower part of the follower connecting rod. The extrusion plug plate is slidably arranged in the extrusion groove. Hydraulic oil is provided in the extrusion groove and the pushing groove;

[0017] When the clamping rod slides to the uppermost end of the guiding groove, the lifting block rotates to the lowermost end of the movable groove. The stepping lifting support assembly and the extended protection enclosure assembly move downwards. The plane of the bottom wall of the counterweight block is tangent to the lower end of the universal wheel. The extrusion plug plate moves upwards in the extrusion groove, and the extension plate slides into the pushing groove;

[0018] When the outward-facing elastic anti-collision component is impacted, since the elastic bending plate protrudes outward in an arc shape, the external impact first squeezes the two-way telescopic connecting plate or the follower plate, causing it to move towards the support housing or the side baffle, and then rapidly deforming the elastic bending plate of the high-elastic composite material. Since the fixed connecting rod and the movable connecting rod are respectively fixed to the upper ends of the support housing and the convex plate, when the elastic bending plate deforms, it pushes the second two-way telescopic rod and the follower connecting rod towards the return plate. The return spring provides a certain buffering force, and the follower connecting rod drives the extrusion plug plate to move downward. The extrusion plug plate is pressed into the extrusion groove. Under the push of the hydraulic oil, the extension plate extends out of the push-out groove, increasing the covering area of the counterweight block, and preventing the device from tipping inward under impact and causing injury to personnel; when the impact is removed, the elastic bending plate rebounds through its own elasticity and the elasticity of the return spring, thereby driving the follower connecting rod to reset, the extrusion plug plate to move upward, and the extension plate to retract back into the push-out groove, without occupying extra space.

[0019] Further, the connecting mechanism includes a stretching box, a connecting cylinder, and a connecting rod. The stretching box is arranged on the side wall of the side baffle on one side away from the second cross rod. A connecting belt is wound inside the stretching box, and a torsion spring is arranged on the connecting belt rotating shaft. The connecting cylinder is connected to the end of the connecting belt and is arranged outside the stretching box. The connecting rod is slidably arranged on the side wall of the side baffle on the other side away from the second cross rod. A compression spring is connected between the upper end of the connecting rod and the side baffle, and the connecting rod is slidably inserted into the connecting cylinder; when multiple sets of this device are connected to each other, the connecting rod is inserted into the connecting cylinder of the device that has been placed. The elastic force of the compression spring presses the connecting rod, and without the operation of the staff, the connecting rod and the connecting cylinder will not separate. Then, the angle between the two side baffles is adjusted, and the connecting belt inside the connecting cylinder adaptively elongates. Under the elastic action of the torsion spring, the connecting belt always remains in a taut state.

[0020] The beneficial effects achieved by the present invention with the above structure are as follows:

[0021] 1. A protective device for housing construction provided by the present invention adopts the pre-action principle combined with the nested structure, and sets up a stepping and lifting support component. Through the support or offset of the lifting block, the extended protective enclosure component moves up or lands relative to the support housing following the stepping and lifting support component. When the extended protective enclosure component moves up, the device is pushed by the universal wheels. When the extended protective enclosure component lands, the universal wheels are fixed and the counterweight block lands to ensure the stability of the device, enabling the device to quickly switch between being pushed and moved and being stably placed, improving the layout efficiency and transportation efficiency;

[0022] 2. The set extended protection enclosure component, based on the lever principle and the Pythagorean theorem, combined with the meshing structure, enables the adjusting blocks to move towards or away from each other by rotating the bidirectional threaded rod, and through the cross-transition of the first cross rod and the second cross rod, the symmetrical side blocks can be contracted or extended, so that the protection range of the device can be adjusted according to the site limitations or construction needs, and the operation is convenient;

[0023] 3. Utilizing the characteristics of elastic materials combined with the hydraulic principle, a spring-actuated anti-collision component is set. When being impacted externally, the extrusion plug plate is pressed into the extrusion groove, and under the push of the hydraulic oil, the extension plate extends out of the push-out groove, increasing the coverage range of the counterweight block for supporting the non-force-bearing surface, avoiding the device from tipping inward under the impact and causing injuries to personnel; when the impact is removed, the elastic bending plate rebounds through its own elasticity and the elasticity of the return spring, thereby driving the follower connecting rod to reset, the extrusion plug plate moves upward, and the extension plate retracts back into the push-out groove again, without occupying extra space.

[0052] Working principle and working process:

[0053] In the initial state, the clamping rod 54 is at the lowermost end of the guiding groove 14. Under the elastic action of the clamping spring 55, the clamping rod 54 springs into the clamping groove 15 to prevent the rotating rod 53 from rotating under external force. At this time, the lifting block 52 is above the movable groove 16 and jacks up the lower first double telescopic rod 21, thereby driving the stepping lifting support assembly 2 to drive the extended type protective enclosure assembly 3 away from the ground. The entire device is supported by the universal wheels 12 and can be pushed. At the same time, the movable connecting rod 42 is at the lower end of the convex plate 323, the follower connecting rod 44 moves following the second double telescopic rod 43, the follower plate 47 moves following the double telescopic connecting plate 46, and the extrusion plug 410 is inserted into the extrusion groove 326. The extension plate 328 extends out of the ejection groove 327 by a part under the push of the hydraulic oil.

[0054] During specific use, under the lifting of the stepping mechanism 5, the entire device is supported by the universal wheels 12, which is convenient for the staff to push and transport. After pushing multiple groups of this device to the housing construction site, arrange them around the construction site with one side of the adjusting rotary handle 27 facing the construction site and the elastic anti-collision component 4 facing outward. Then, rotate the adjusting rotary handle 27 according to site limitations or construction needs. The adjusting wheel 29 meshes with the screw tooth 28. By rotating the adjusting rotary handle 27, the double threaded rod 26 rotates. The rotating double threaded rod 26 drives the adjusting blocks 311 engaged with its two ends to move towards or away from each other. When the symmetrically arranged upper and lower adjusting blocks 311 move towards each other, one end of the first cross rod 312 connected to them moves towards each other. Under the restriction of the cross rotation axis of the first cross rod 312, the end of the first cross rod 312 close to the adjusting block 311 adaptively expands and contracts. According to the lever principle and the Pythagorean theorem, the end of the first cross rod 312 connected to the transition block 314 also moves towards each other, thereby causing the transition block 314 to slide on the transition rod 313 while pushing the transition rod 313 outward, thus driving the end of the second cross rod 315 connected to the transition block 314 to move towards each other, and then pushing the side blocking block 321 to expand and move outward. The first double telescopic rod 21 with a three-section telescopic structure adaptively extends according to the moving distances of the transition rod 313 and the side blocking block 321. The second double telescopic rod 43 and the double telescopic plate, both with a three-section telescopic structure, also adaptively extend, thereby expanding the overall width of this device and increasing the protection range. Similarly, when the symmetrically arranged upper and lower adjusting blocks 311 move away from each other, driven by the first cross rod 312 and the second cross rod 315, the symmetric side blocking blocks 321 move inwards and contract, thus reducing the protection range, and the adjustment is convenient.

[0055] When the overall width of the device is adjusted, step on the pedal 56, and the clamping spring 55 is compressed, causing the clamping rod 54 to move out of the restriction of the clamping groove 15 and into the guiding groove 14. At the same time, step on the clamping rod 54 towards the arc trajectory position of the guiding groove 14. At this time, the rotating rod 53 drives the rotating column 51 to rotate, and then drives the lifting block 52 to rotate. The clamping rod 54 moves along the arc trajectory of the guiding groove 14 to the uppermost end of the guiding groove 14, and the lifting block 52 rotates to the lowermost end of the moving groove 16, no longer supporting the first double telescopic rod 21 below. The stepping lifting support assembly 2 and the extended protective enclosure assembly 3 move downward, and the plane of the bottom wall of the counterweight block 322 is tangent to the lower end of the universal wheel 12. The counterweight block 322 falls to the ground, and the pressure rod 23 moves downward in the pressure groove 17, pressing the pressure cylinder 24 onto the universal wheel 12. The rubber pad 25 inside it contacts and squeezes against the universal wheel 12. Under the friction restriction of the rubber pad 25, the universal wheel 12 is difficult to rotate and only provides support force, improving the stability of the device. At the same time, the movable connecting rod 42 moves upward relative to the side baffle 321 to the upper end of the convex plate 323, and the follower connecting rod 44 moves upward on the side wall of the side baffle 321, driving the extrusion plug 410 to move upward in the extrusion groove 326, and then sliding the extension plate 328 into the push-out groove 327. Subsequently, water is injected into the side baffle 321 and the counterweight block 322 through the liquid inlet hole 325 to increase the overall weight of the device and ensure the stability of the device during use.

[0056] After completing the adjustment of the protection range and the placement of the position of one set of this device, perform the adjustment of the protection range of the next set of this device according to the above steps, and insert the connecting rod 333 into the connecting cylinder 332 on the already placed device. The elastic force of the compression spring 334 presses the connecting rod 333. Without the operation of the staff, the connecting rod 333 and the connecting cylinder 332 will not separate. Subsequently, adjust the angle between the two side baffles 321. The connecting belt in the connecting cylinder 332 adaptively elongates. Under the elastic action of the torsion spring, the connecting belt always remains in a taut state. After adjusting the relative position, step on the pedal 56 according to the above steps to make the counterweight block 322 land, and the arrangement operation is convenient.

[0057] When the outward-facing elastic anti-collision component 4 is impacted, since the elastic bending plate 45 protrudes outward in an arc shape, the external impact preferentially presses on the bidirectional telescopic connecting plate 46 or the follower plate 47, causing it to move towards the support housing 1 or the side stop 321. As a result, the elastic bending plate 45 made of a highly elastic composite material rapidly deforms. Since the fixed connecting rod 41 and the movable connecting rod 42 are respectively fixed to the upper ends of the support housing 1 and the convex plate 323, when the elastic bending plate 45 deforms, it pushes the second bidirectional telescopic rod 43 and the follower connecting rod 44 towards the return plate 48. The return spring 49 provides a certain buffering force, and the follower connecting rod 44 drives the extrusion plug 410 to move downward. The extrusion plug 410 is pressed into the extrusion groove 326. Under the push of the hydraulic oil, the extension plate 328 extends out of the push-out groove 327, increasing the coverage area of the counterweight 322, and preventing the device from tipping inward under impact and causing injury to personnel. When the impact is removed, the elastic bending plate 45 rebounds through its own elasticity and the elasticity of the return spring 49, thereby driving the follower connecting rod 44 to reset. The extrusion plug 410 moves upward, and the extension plate 328 retracts back into the push-out groove 327 again, without occupying extra space.

[0058] When the device needs to be recycled, the water inside the side stop 321 and the counterweight 322 is drained through the liquid outlet plug 324. Lift the connecting rod 333 to disconnect it from the connecting cylinder 332. The connecting belt is rewound back into the stretching box 331 under the action of the torsion spring. Subsequently, step on the pedal 56 downward, causing the positioning rod 54 to slide along the arc trajectory of the guiding groove 14 to the lowest end of the guiding groove 14. At this time, the lifting block 52 rotates again and is clamped below the lower first bidirectional telescopic rod 21, supporting the stepping and lifting type support assembly 2 and the extended type protective enclosure assembly 3. The pressing cylinder 24 no longer restricts the universal wheel 12. Slowly remove the foot pressure. Under the elastic action of the positioning spring 55, the positioning rod 54 slides into the positioning groove 15 for positioning. Subsequently, by adjusting the turning handle 27, the side stop 321 is retracted and the device can be recycled by pushing it with the universal wheel 12.

[0059] It should be noted that the three-stage telescopic structure is a prior art and will not be elaborated here.

[0060] The above is the overall working process of the present invention, and this step can be repeated during the next use.
