Description

Technical Field

[0001] The present invention belongs to the technical field of construction equipment, and particularly relates to a hoist for building construction that is convenient for maintenance. Background Art

[0002] In the field of civil house construction, in order to enhance the aesthetic beauty of the building appearance, construction workers often choose colorfully decorated and variously shaped ceramic tiles to decorate and lay the outer wall of the building. After the ceramic tiles are laid, they need to go through a drying and curing process to ensure their firm adhesion to the wall. However, affected by various factors such as construction technology and material quality, some ceramic tiles may show hollowing phenomenon after drying, forming "hollow bricks". These seemingly intact but potentially dangerous ceramic tiles, over time, due to factors such as environmental temperature changes and slight wall displacements, the bonding force gradually weakens, and there is a risk of falling at any time, which not only affects the building beauty but also poses a serious threat to the safety of passing pedestrians and surrounding property. Therefore, timely breaking and repairing the problematic ceramic tiles to eliminate potential safety hazards is a necessary measure to ensure the safety and beauty of civil house use.

[0003] Currently, when repairing the ceramic tiles on the building facade, a hoist device is usually required for high-altitude operations. For the hoist device, there are many existing technologies, such as: The prior art with the publication number CN211569971 discloses a mobile hoist for buildings, including two groups of identical support columns. The outside of one group of support columns is sleeved with movable columns. The bottoms of two vertical rods are hinged with a baffle through a hinge. Both sides of the top of the top cover are fixedly installed with bearing seats. Both inner parts of the two bearing seats are rotationally connected with a rotating shaft through bearings. Both sides of the rotating shaft are rotationally connected with winding rollers. The first pulley is connected with the second pulley through a belt. Four corners at the bottom end of the bottom plate are fixedly connected with moving wheels. This solution is convenient for moving the hoist through the four corners at the bottom end of the bottom plate being fixedly connected with moving wheels; the shock feeling is reduced and the stability is increased through the shock-absorbing springs fixedly arranged inside the support plate; since the bottoms of the two vertical rods are hinged with a baffle through a hinge, the opening angle of the baffle can be adjusted to facilitate the transportation of materials; through the connecting rod, it is convenient for the staff to repair the structure at the top.

[0004] However, in the actual use process, there are still some problems: 1. In the current use process of traditional hoist devices, during operation, the operators not only need to frequently control the hoist for precise positioning but also need to perform breaking operations. Long-term repetitive labor is likely to cause occupational health problems such as lumbar muscle strain, greatly increasing the labor intensity of front-line workers; 2. During the repair and maintenance of hollow bricks, due to the lack of effective protection and automatic control mechanisms, the flying ceramic tile fragments and wall debris during crushing may cause accidental injuries such as cuts and bruises to the operators, posing potential safety hazards to the repair and maintenance operations. Summary of the Invention

[0005] The object of the present invention is to provide a hoist for building construction that is convenient for repair and maintenance, eliminating the need for operators to perform high-altitude manual crushing operations and reducing the labor intensity of the workers during the crushing operation.

[0006] The technical solution adopted by the present invention is a hoist for building construction that is convenient for repair and maintenance, including a moving frame. A lifting seat is provided at the top of the moving frame, and a workbench is installed on the top of the lifting seat. A moving component is provided on the workbench. The moving component includes a motor fixed on one side of the workbench. The output end of the motor is connected to a lead screw. A base is movably connected to the lead screw, and the base moves horizontally relative to the lead screw. A crushing component for impacting and crushing the exterior wall hollow bricks is installed on the base. A collecting component is provided on the workbench below the crushing component.

[0007] The present invention is further characterized in that The crushing component includes crushing rods located at opposite ends of the base. The crushing rod includes a moving rod and an impact head. The impact head is fixed to one end of the moving rod. The base has a frame structure with an open upper end. The other end of the moving rod passes through the side plate of the base and is connected to a base plate. A compression spring is sleeved on the moving rod. One end of the compression spring abuts against the base plate, and the other end abuts against the side plate of the base. An extrusion component for reciprocally impacting the opposite base plates is provided between the two base plates.

[0008] The impact head is made of solid metal, and the collecting component is located below the impact head.

[0009] A splash guard is provided on the side of the moving rod close to the impact head. The splash guard is in a horn shape, and the diameter of the impact head is smaller than the opening diameter of the splash guard.

[0010] The extrusion component includes a vertical plate and a rack. The vertical plate is connected to the base. An eccentric wheel is provided on one side of the vertical plate. The eccentric wheel is located between the two base plates, and a driven gear rod is connected to one side of the eccentric wheel. The driven gear rod passes through the vertical plate and is connected to a driven gear. The rack is fixed to the top of the workbench. A double-headed gear rod is provided on one side of the rack. The gear at one end of the double-headed gear rod meshes with the rack, and the gear at the other end meshes with the driven gear.

[0011] Guide rods for improving the horizontal movement stability of the base are further provided at the bottom of the base. The guide rods are movably connected to the base.

[0012] The collection components include collection boxes arranged on both sides of the workbench. The workbench is in a frame structure with an open bottom end. On the inner side of the workbench, opposite to the side of the collection box, a pair of cylindrical tubes are respectively fixed. A sliding rod is movably connected inside the cylindrical tube. The sliding rod passes through the side plate of the workbench and is connected to the collection box. An elastic member is arranged inside the cylindrical tube. One end of the elastic member abuts against the bottom of the sliding rod, and the other end abuts against the cylindrical tube.

[0013] The top of the side wall of the collection box is a slope, and the slope inclines towards the inside of the collection box. A rotating plate is arranged on one side wall of the collection box, and a stopper for opening and closing the rotating plate is also installed outside the collection box.

[0014] The outer edge of the collection box extends to the outside of the lifting seat.

[0015] A cylinder is installed on one side of the collection box. The piston rod of the cylinder passes through the side wall of the collection box and is connected to a slope-shaped plate. The slope-shaped plate is located inside the collection box and fits with the bottom of the collection box.

[0016] The beneficial effects of the present invention are as follows: (1) For the hoist for building construction that is convenient for maintenance in the present invention, when the outer wall of the collection box fits against the wall surface, the collection box is subjected to the extrusion force of the wall. The sliding rod provided at the end of the collection box slides on the inner wall of the cylindrical tube, and at the same time, the sliding rod squeezes the elastic member. During this process, the collection box fits tightly against the wall surface. When the breaking rod breaks the ceramic tile, the collection box under the breaking rod collects the generated ceramic tile debris, reducing the labor intensity of the operators.

[0017] (2) In the hoist for building construction that is convenient for maintenance in the present invention, the splash guard blocks the debris. When the breaking rod impacts the hollow brick, the generated debris is blocked by the splash guard to avoid splashing, thus protecting the safety of nearby pedestrians and improving the safety of the maintenance operation.

[0018] (3) In the hoist for building construction that is convenient for maintenance in the present invention, by controlling the motor to drive the screw rod to rotate, the base provided on the surface of the screw rod moves horizontally relative to the screw rod. During the movement of the base, the ceramic tile is impacted by the horizontal synchronous reciprocating movement of the breaking rod, so as to facilitate the all-round breaking of the surface of the hollow brick.

[0019] (4)In the hoist for building construction that is convenient for maintenance according to the present invention, when the motor drives the screw rod to rotate, the base moves horizontally relative to the screw rod. During the movement of the base, the double-headed gear rod is driven to move. When the double-headed gear rod moves, it meshes and rotates on one side of the rack. When the double-headed gear rod rotates, it drives the driven gear rod to rotate. The eccentric wheel provided at the end of the driven gear rod rotates. During the rotation of the eccentric wheel, the end of the substrate is reciprocally extruded, so that the crushing rod provided at the end of the substrate reciprocates. During the reciprocating movement of the crushing rod, the hollow bricks are impacted, thereby improving the maintenance efficiency. Description of the Drawings

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] Embodiment 1 The hoist for building construction that is convenient for maintenance according to the present invention, as Figure 1 and Figure 2 shown, includes a moving frame 100. A lifting seat 101 is provided at the top of the moving frame 100. A workbench 102 is installed at the top of the lifting seat 101. A moving component is provided on the workbench 102, as Figure 3 shown. The moving component includes a motor 201 fixed to one side of the workbench 102. The output end of the motor 201 is connected to a lead screw 202. A base 203 is movably connected to the lead screw 202. The base 203 moves horizontally relative to the lead screw 202. A crushing component 300 for impacting and crushing the hollow bricks on the outer wall is installed on the base 203. A collecting component 400 is provided on the workbench 102 below the crushing component 300. The collecting component 400 is used for collecting the tiles that are impacted and crushed, so that the fragments falling into the collecting component 400 are evenly distributed.

[0024] Embodiment 2 The hoist for building construction that is convenient for maintenance according to the present invention, as Figure 1 and Figure 2 shown, includes a moving frame 100. A lifting seat 101 is provided at the top of the moving frame 100. A workbench 102 is installed at the top of the lifting seat 101. A moving component is provided on the workbench 102.

[0025] As Figure 3 shown, the moving component includes a motor 201 provided on one side of the workbench 102. A lead screw 202 is provided at the output end of the motor 201. A base 203 is provided on the surface of the lead screw 202. The base 203 moves horizontally on the surface of the lead screw 202. A guide rod for improving the horizontal movement stability of the base 203 is further provided at the bottom of the base 203. The guide rod is movably connected to the base 203.

[0026] Crushing components 300 are provided on both sides of the surface of the base 203. The crushing components 300 are used for impacting and crushing the hollow bricks on the outer wall. Collecting components 400 are provided on both sides of the workbench 102. The collecting components 400 are used for collecting the tiles that are impacted and crushed.

[0027] Considering that during the construction of civilian houses, in order to improve the aesthetics, tiles are usually attached to the outer wall surface. During the attachment process, the cement added between the tiles and the wall slides under the action of gravity, which is likely to cause the tiles to be hollow. Tiles that are hollow for a long time are likely to fall, causing potential safety hazards. After the tiles are attached, it is necessary to inspect the tiles. When the tiles are hollow, due to the high outer wall, it is inconvenient to crush them. Therefore, as Figure 3 and Figure 4As shown in the figure, in this embodiment, the crushing assembly 300 includes crushing rods 301 located at opposite ends of the base 203. The crushing rod 301 includes a moving rod and an impact head. The impact head is fixed to one end of the moving rod and is made of solid metal. The base 203 has a frame structure with an open upper end. The other end of the moving rod passes through the side plate of the base 203 and is connected to a substrate 302. A compression spring 303 is sleeved on the moving rod. One end of the compression spring 303 abuts against the substrate 302, and the other end abuts against the side plate of the base 203. An extrusion assembly 500 for reciprocally impacting the opposite substrate 302 is provided between the two substrates 302.

[0028] That is, by pressing the substrate 302, the crushing rod 301 is driven to move horizontally to impact and crush the hollow brick. Move the moving frame 100 to the wall to be repaired, and control the lifting seat 101 to drive the workbench 102 to move vertically upward until it reaches the position of the hollow brick. The extrusion assembly 500 pushes the substrate 302 to drive the crushing rod 301 to move horizontally. Since the impact head of the crushing rod 301 is made of solid metal, the crushing rod 301 can quickly crush the hollow brick when it collides with the hollow brick. When the crushing rod 301 impacts the wall, stop pushing the substrate 302. At this time, the substrate 302 is reset under the action of the compression spring 303, which is convenient for repeated impact crushing and quickly repairs the hollow position. At the same time, control the motor 201 to drive the lead screw 202 to rotate. The base 203 provided on the lead screw 202 moves horizontally relative to the lead screw 202. During the movement of the base 203, the crushing rod 301 repeatedly moves horizontally to impact the ceramic tile, realizing all-round crushing of the surface of the hollow brick.

[0029] Embodiment 3 On the basis of the above Embodiment 2, in this embodiment, considering that during the crushing of the hollow brick, when the ceramic tile is broken by the impact force of the crushing rod 301, the residue is likely to splash. When there are pedestrians nearby, it is easy to cause potential safety hazards and injure pedestrians. Therefore, as Figure 5 shown, the building hoist for convenient maintenance of the present invention is provided with a splash guard 304 at the end of the crushing rod 301. The splash guard 304 is in a horn shape, and the diameter of the impact head is smaller than the opening diameter of the splash guard 304.

[0030] When crushing the hollow brick, the splash guard 304 blocks the crushed slag. By providing the splash guard 304 at the end of the crushing rod 301, when the crushing rod 301 impacts the hollow brick, the generated debris is blocked by the splash guard 304 to avoid splashing, thereby protecting the safety of nearby pedestrians and improving the safety of the maintenance operation.

[0031] Embodiment 4 On the basis of the above Embodiment 3, as Figure 4 and Figure 6As shown in the figure, in the hoist for building construction that is convenient for maintenance according to the present invention, the extrusion assembly 500 includes a vertical plate 204 and a rack 501. The vertical plate 204 is connected to the base 203. An eccentric wheel 504 is arranged on one side of the vertical plate 204. The eccentric wheel 504 is located between the two side substrates 302. And a driven gear rod 503 is connected to one side of the eccentric wheel 504. The driven gear rod 503 passes through the vertical plate 204 and is connected to a driven gear; The rack 501 is fixed to the top of the workbench 102. A double-headed gear rod 502 is arranged on one side of the rack 501. The gear at one end of the double-headed gear rod 502 meshes with the rack 501, and the gear at the other end meshes with the driven gear.

[0032] When the motor 201 drives the lead screw 202 to rotate, the base 203 moves horizontally on the surface of the lead screw 202. During the movement of the base 203, it drives the double-headed gear rod 502 to move. When the double-headed gear rod 502 moves, it meshes and rotates on one side of the rack 501. When the double-headed gear rod 502 rotates, it drives the driven gear rod 503 to rotate. The eccentric wheel 504 provided at the end of the driven gear rod 503 rotates. During the rotation of the eccentric wheel 504, it reciprocally extrudes the end of the substrate 302, causing the crushing rod 301 provided at the end of the substrate 302 to move reciprocally. During the reciprocating movement of the crushing rod 301, it impacts the hollow brick, thereby improving the maintenance efficiency.

[0033] Embodiment 5 On the basis of the above Embodiment 4, in this embodiment, when crushing the hollow brick, in order to facilitate its collection and reduce the labor intensity of the operators, the collection assembly 400 is located below the impact head, as Figure 7 and Figure 8 shown. The collection assembly 400 includes collection frames 404 arranged on both sides of the workbench 102. The outer edge of the collection frame 404 extends to the outside of the lifting seat 101. That is, when imaging the horizontal projection from top to bottom, the outer edge of the lifting seat 101 is located inside the outer edge of the collection frame 404.

[0034] The workbench 102 has a frame structure with an open bottom end. A pair of cylinder barrels 401 are respectively fixed on the inner side of the workbench 102 opposite to the collection frame 404. A slide rod 402 is movably connected inside the cylinder barrel 401. The slide rod 402 passes through the side plate of the workbench 102 and is connected to the collection frame 404; An elastic member 403 is arranged inside the cylinder barrel 401. One end of the elastic member 403 abuts against the bottom of the slide rod 402, and the other end abuts against the cylinder barrel 401.

[0035] Furthermore, the top of the side wall of the collection frame 404 is a slope, and the slope inclines towards the inside of the collection frame 404.

[0036] That is, the collection box 404 drives the sliding rod 402 to slide on the inner wall of the column cylinder 401 by extruding the outer wall. When the moving frame 100 moves to the construction position, the outer wall of the collection box 404 is adjusted to fit the wall surface by finely adjusting the position of the moving frame 100. When the collection box 404 fits the wall surface, the collection box 404 is subjected to the extrusion force of the wall, and the sliding rod 402 provided at the end of the collection box 404 slides on the inner wall of the column cylinder 401. At the same time, the sliding rod 402 squeezes the elastic member 403. During this process, the collection box 404 is closely attached to the wall surface. When the crushing rod 301 crushes the tiles, the collection box 404 under the crushing rod 301 automatically collects the generated tile debris.

[0037] Example 6 Based on the above Example 5, when the collection in the collection box 404 is completed, in order to facilitate the cleaning of the collected tile debris, a rotating plate 405 is provided on one side wall of the collection box 404. There are stoppers on both sides of the rotating plate 405. The stoppers are movably connected to the collection box 404. When the stopper is rotated to the end of the rotating plate 405, its position is fixed. The stopper is rotated away from the rotating plate 405, and the debris is pushed out through the rotating plate 405, so as to facilitate the cleaning of the tile debris collected in the collection box 404.

[0038] Since the sizes of the debris collected inside the collection box 404 are different, the utilization rate of the internal space of the collection box 404 is low, and the inside of the collection box 404 needs to be cleaned frequently, resulting in low maintenance efficiency. Therefore, a cylinder 406 is installed on one side of the collection box 404. The piston rod of the cylinder 406 passes through the side wall of the collection box 404 and is connected to a slope-shaped plate 407. The slope-shaped plate 407 is located inside the collection box 404 and fits the bottom of the collection box 404.

[0039] Control the piston rod at the end of the cylinder 406 to drive the slope-shaped plate 407 to move horizontally. During the movement of the slope-shaped plate 407, the debris collected inside the collection box 404 is shaken, so that the residues fill each other, improving the space utilization rate of the collection box 404 and the maintenance efficiency.

[0040] In this specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.

[0041] The foregoing description of the disclosed embodiments enables those skilled in the art to practice or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
