[0002] Construction engineering refers to all kinds of buildings and engineering facilities that provide material and technical foundations for human life and production. Construction engineering is an organized, purposeful, and large-scale economic activity of human beings. When construction is carried out, it is necessary to lay building pipelines such as buried drainage pipes (sewage pipes) and buried cable pipes. When laying such building pipelines, due to the complex site environment, it is difficult for large transportation equipment to enter. Small hoisting devices are needed to hoist and transfer them to the laying position to avoid the phenomenon of laborious manual lifting.

When hoisting and transferring building pipelines, the steel wire rope of the hoist is prone to swaying due to its flexibility, posing a certain safety hazard and resulting in unsatisfactory hoisting and transfer stability; 2. The lack of an integrated safety support structure for hoisting building pipelines poses a risk of accidental fall of building pipelines, resulting in injury to personnel and unsatisfactory safety. In view of this, this application proposes a building engineering hoisting structure to solve the above-mentioned problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4 As shown in this embodiment, a construction hoisting structure includes a U-shaped top plate 1. Support plates 101 are fixedly connected to both sides of the bottom of the U-shaped top plate 1. Rectangular support sleeves 102 are fixedly connected to the bottom of the support plates 101. Two locking casters 103 are rotatably mounted on the bottom of the rectangular support sleeves 102. An electric hoist 4 is fixedly installed on the top of the U-shaped top plate 1. The bottom end of the wire rope of the electric hoist 4 extends to the bottom of the U-shaped top plate 1 and is fixedly installed on a box-shaped lifting plate 2 with an open bottom. A rope ring fixedly welded to the top of the box-shaped lifting plate 2 and fixedly installed with the wire rope is also fixedly installed. Rope holes are provided at both the top and bottom of the U-shaped top plate 1. The wire rope of the electric hoist 4... The box-shaped lifting plate 2 is slidably mounted on two support plates 101 inside the rope hole and without contacting the inside of the rope hole. The top of the box-shaped lifting plate 2 has two rectangular guide holes that slide and fit with the outer side of the corresponding support plate 101, which serve to guide the vertical sliding of the box-shaped lifting plate 2. The box-shaped lifting plate 2 is equipped with a clamping component for clamping building pipe fittings. The electric hoist 4 is used to lower and lift the box-shaped lifting plate 2. The clamping component is used to clamp the building pipe fittings simultaneously from both sides. The clamped building pipe fittings are lifted when the box-shaped lifting plate 2 is raised. The two support plates 101 are used to vertically guide the box-shaped lifting plate 2 to prevent swaying during the transfer after lifting.

[0025] The same linkage-type relative displacement support anti-fall assembly is installed inside the two rectangular support sleeves 102. The top of the linkage-type relative displacement support anti-fall assembly extends into the U-shaped top plate 1. A drive motor 306 with an output shaft fixedly connected to the linkage-type relative displacement support anti-fall assembly is fixedly installed on the top left side of the U-shaped top plate 1. The linkage-type relative displacement support anti-fall assembly is used to perform safe anti-fall work on the support of the raised building pipes at the bottom when the drive motor 306 is started.

[0026] Specifically, the clamping assembly includes two rectangular sleeves 201 slidably fitted on the outside of the box-shaped lifting plate 2. Screws 204 are rotatably mounted on the inner walls of both sides of the box-shaped lifting plate 2. First bearings are fixedly connected to the inner walls of both sides of the box-shaped lifting plate 2, with the inner rings of the first bearings fixedly fitted to the outer sides of the corresponding screws 204, thus achieving the effect of rotating the screws 204. A dual-axis motor 203 is fixedly mounted on the top inner wall of the box-shaped lifting plate 2. The two output shaft ends of the dual-axis motor 203 are respectively fixedly connected to the ends of the two screws 204 that are close to each other. The threads of the two screws 204 have opposite directions. A transverse sliding seat 205 is threaded onto the screw 204 and fixedly connected to the bottom inner wall of the corresponding rectangular sleeve 201. A threaded hole is opened on one side of the transverse sliding seat 205 for threaded connection with the corresponding screw 204. Utilizing the threaded connection between the screw 204 and the threaded hole, and the opposite direction of the threads of the two screws 204, it is convenient to drive the two transverse sliding seats 204 when the two screws 204 rotate. 05. The effect of similar or repulsive displacement: Two V-shaped clamping blocks 202 are welded and fixed to the bottom of the rectangular sliding sleeve 201. The two V-shaped clamping blocks 202 are symmetrically arranged on the left and right sides. V-shaped anti-slip pads are glued and fixed to the inner side of the V-shaped clamping blocks 202. The V-shaped anti-slip pads are used to enhance the anti-slip performance when clamped. A storage battery is fixedly installed on the top right side of the U-shaped top plate 1. The electric hoist hoist 4, the dual-shaft motor 203, and the drive motor 306 are all electrically connected to the storage battery; the rectangular sliding sleeve 201... The screw 204, the transverse sliding seat 205, the dual-axis motor 203, and the V-shaped clamping block 202 work together. The dual-axis motor 203 drives the two screws 204 to rotate synchronously. By using the opposite direction of the threads of the two screws 204, the rotation of the two screws 204 drives the two transverse sliding seats 205 to move close to each other. The two transverse sliding seats 205 drive the two rectangular sliding sleeves 201 to move close to each other. The two rectangular sliding sleeves 201 drive the V-shaped clamping blocks 202 on both sides to move close to each other, so as to achieve the effect of clamping the building pipe fittings synchronously from both sides.

[0027] Furthermore, the linkage-type relative displacement support anti-fall assembly includes two U-shaped support plates 3, which are slidably fitted into corresponding rectangular support sleeves 102. Racks 301 are fixedly connected to the rear inner wall of the left U-shaped support plate 3 and the front inner wall of the right U-shaped support plate 3. Gears 302 mesh with the front of the left rack 301 and the rear of the right rack 301. A rotating shaft 303 is fixedly connected to the top of each gear 302. The top ends of both rotating shafts 303 extend into the U-shaped top plate 1 and are fixedly connected to synchronous pulleys 304. The top of the support plate 101 has a circular through hole. The rotating shaft 303 is located in the corresponding circular through hole and does not contact the inner wall of the circular through hole, so as to allow the rotating shaft 303 to move through. The U-shaped top plate 1 is rotatably sleeved on the two rotating shafts 303, and the rectangular support sleeve 102 is rotatably sleeved on the corresponding rotating shaft 303. Circular through holes are provided on both sides of the bottom of the U-shaped top plate 1 and the top of the rectangular support sleeve 102. A second bearing is fixedly sleeved in the circular through hole. The inner ring of the second bearing is fixedly sleeved with the outer side of the corresponding rotating shaft 303, so as to enable the rotating installation of the rotating shaft 303. As a result, the two synchronous pulleys 304 are connected to the same synchronous belt 305. The top of the left synchronous pulley 304 is fixedly connected to the bottom of the output shaft of the drive motor 306. The wire rope of the electric hoist 4 is located inside the synchronous belt 305 and does not contact its inner side. The provided loop support plate 3, rack 301, gear 302, rotating shaft 303, synchronous pulley 304 and synchronous belt 305 cooperate to drive the left synchronous pulley 304 to rotate after the building pipe is lifted. The left synchronous pulley 304 is driven by the synchronous belt 305. 05 drives the right-side synchronous wheel 304 to rotate. The two synchronous wheels 304 drive the two gears 302 to rotate through the two rotating shafts 303. Since the two gears 302 mesh with the two racks 301 on the front and rear sides respectively, when the two gears 302 rotate, they drive the two racks 301 to move close together. The two racks 301 drive the two U-shaped support plates 3 to move close together and abut against each other. The two U-shaped support plates 3 that abut against each other support the building pipes at the bottom after lifting, preventing the risk of building pipes falling accidentally during hoisting and transfer, and improving the safety of use.

[0028] The usage method of this embodiment is as follows: When using this construction hoisting structure, push the device to move it to the location of the construction pipe to be hoisted via four locking universal wheels 103, so that the construction pipe is located below the center of the four V-shaped clamps 202. Start the electric hoist 4 in the forward direction so that its own wire rope lowers the box-shaped lifting plate 2. At this time, the box-shaped lifting plate 2 slides downward on the two support plates 101 to perform vertical downward movement. The box-shaped lifting plate 2 drives the four V-shaped clamps 202 to move downward through the two rectangular sliding sleeves 201. After the four V-shaped clamps 202 move down to both sides of the construction pipe, start the dual-shaft motor 203 in the forward direction to drive the two screws 204 to rotate synchronously. By using the opposite screw threads of the two screws 204, the rotation of the two screws 204 drives the two transverse sliding seats 205 to move close to each other. The seat 205 drives two rectangular sliding sleeves 201 to slide close together on the box-shaped lifting plate 2. The two rectangular sliding sleeves 201 drive the V-shaped clamps 202 on both sides to move close together. The four V-shaped clamps 202 on both sides drive four V-shaped anti-slip rubber pads to clamp the building pipe in the middle. After clamping, the electric hoist 4 is started in reverse to lift the box-shaped lifting plate 2 through its own wire rope. The box-shaped lifting plate 2 slides upward on the two support plates 101. At the same time, the box-shaped lifting plate 2 lifts the clamped building pipe through the two rectangular sliding sleeves 201 and the four V-shaped clamps 202 in sequence. The two support plates 101 are used to achieve the effect of vertically guiding the box-shaped lifting plate 2, thereby achieving the effect of clamping the building pipe and vertically and stably lifting it, avoiding the phenomenon of the building pipe swinging back and forth when moving after lifting, reducing safety hazards, and improving the stability of hoisting and transfer.

[0029] After the building pipe is lifted, the forward start drive motor 306 drives the left synchronous wheel 304 to rotate. The left synchronous wheel 304 drives the right synchronous wheel 304 to rotate through the synchronous belt 305. The two synchronous wheels 304 drive the two gears 302 to rotate through the two rotating shafts 303. Since the two gears 302 mesh with the two racks 301 on the front and rear sides respectively, when the two gears 302 rotate, they drive the two racks 301 to move close together. The two racks 301 drive the two U-shaped support plates 3 to slide close together and abut against each other in the two rectangular support sleeves 102. Then, the building pipe can be lowered to the top of the two U-shaped support plates 3 while still in the hoisting state using the electric hoist hoist 4. The two U-shaped support plates 3 abut against each other at the bottom to support the lifted building pipe, achieving the effect of integrated safe support at the bottom when hoisting the building pipe, reducing the risk of accidental fall of the building pipe or injury to personnel, and improving the safety of use.

[0030] After being transferred to the laying position, the drive motor 306 is started in reverse, which is completely opposite to the direction of movement of the drive motor 306 started in the forward direction. At this time, the two U-shaped support plates 3 move in opposite directions, releasing the support state. Then, the electric hoist hoist 4 is used to lower the building pipe down to the ground. Then, the dual-shaft motor 203 is started in reverse, which is completely opposite to the direction of movement of the dual-shaft motor 203 started in the forward direction. At this time, the V-shaped clamps 202 on both sides move in opposite directions and release the clamping state on the building pipe. The hoisting and transfer are completed, and the laying work can be carried out.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
