Description

Technical Field

[0001] This utility model belongs to the field of demolition operation technology, and in particular relates to a construction hoisting equipment for demolition operations in confined spaces such as basements. Background Technology

[0002] This is a construction method for removing partition walls in small spaces during phased construction. Basement construction is often carried out in phases with long intervals. In order to ensure the normal use of the basement in the early stages, reinforced concrete partition walls are usually set up to solve the problem of phased delivery of the basement. When the basement is delivered as a whole in the later stages, the partition concrete walls need to be removed.

[0003] When the basement is handed over as a whole in the later stage, the partition walls of the basement need to be removed. During the demolition construction, there are difficulties such as narrow space, inability to enter large equipment, difficulty in material transportation, and high construction risks. The compartmentalized demolition method can be adopted, with wire saws and table saws in conjunction with small lifting tools. Before the demolition operation, the basement roof should be backfilled and deformation should be monitored throughout the process. The use of small lifting tools can assist the demolition operation in the narrow space of the basement, thereby improving the economic benefits and construction efficiency of the demolition operation.

[0004] When using small lifting tools to lift and transport wall blocks after the partition wall has been removed, lifting clamps can be used to hold the wall blocks. Lifting clamps have the advantages of no power loss, simple structure, and high clamping efficiency. However, when the lifting clamp is used to hold the wall block at the top of the partition wall, the clamp itself is inconvenient to open, and opening the lifting clamp at a height is a high-altitude operation with poor safety. Therefore, a lifting equipment for demolition operations in confined spaces of basements is needed. By setting guide wheels at the top of the lifting clamp and guiding the pull rope through the guide wheels, personnel on the ground can control the opening and closing of the lifting clamp by pulling the rope. This allows the lifting clamp to hold the wall block at a height, thereby improving the convenience of lifting and transporting wall blocks during demolition operations in confined spaces of basements and optimizing work efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a hoisting device for demolition operations in confined spaces like basements. A guide wheel is installed at the top of the hoisting clamp, which guides the pull rope, allowing personnel on the ground to control the opening and closing of the hoisting clamp via the pull rope. This enables the hoisting clamp to hold wall blocks at higher locations, improving the ease of hoisting wall blocks during demolition operations in confined basement spaces, optimizing work efficiency, and solving the aforementioned technical problems.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A hoisting equipment for demolition operations in a confined space of a basement includes a frame: a hoisting arm is rotatably mounted on the top of the frame via a pivot shaft; a cylinder is rotatably mounted on the surface of the frame via a pivot shaft; the output end of the cylinder is rotatably connected to the hoisting arm via a pivot shaft; a hanging chain is attached to the end of the hoisting arm; a channel steel beam is fixedly connected to the end of the hanging chain; a slotted horizontal plate is provided on the top of the channel steel beam; a clamping block is provided on the outer side of the channel steel beam; a bolt rod is installed between the slotted horizontal plate and the clamping block; a nut block is threadedly connected to the surface of the bolt rod; a guide wheel is installed on the top of the slotted horizontal plate; a hoisting clamp is installed at the bottom of the channel steel beam; a protruding rod is integrally formed on the surface of the hoisting clamp; a pull rope is fixedly connected to the surface of the protruding rod; and the surface of the pull rope is in contact with the guide wheel.

[0007] The present invention provides a lifting and hoisting device for demolition operations in confined spaces of basements, as described above. Further, the hoisting arm is a telescopic arm, and a pin is installed on the surface of the hoisting arm.

[0008] The above-described hoisting equipment for demolition operations in confined spaces of a basement is further characterized by the following: the clamping block and the slotted horizontal plate are both in contact with the surface of the channel steel beam, and the surface of the bolt rod is fitted with an elastic washer.

[0009] The present invention further comprises the following: the hoisting equipment for demolition operations in confined spaces of basements as described above, wherein the hoisting clamp is provided with a clamping plate welded to its end, and the clamping plate is a stainless steel clamping plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model utilizes the combined use of clamping blocks and bolt rods to fix the slotted horizontal plate to the top of the channel steel beam. The movement of the channel steel beam then moves the lifting clamp to the top of the partition wall. The release of the pull rope removes the tension on the protruding member, allowing the bottom of the lifting clamp to close and abut against the outside of the wall block. The upward movement of the channel steel beam then tightens the lifting clamp, securing and lifting the wall block. By installing guide wheels at the top of the lifting clamp and guiding the pull rope, personnel on the ground can control the opening and closing of the lifting clamp via the pull rope. This allows the lifting clamp to hold the wall block at a height, improving the ease of wall block lifting during demolition work in confined underground spaces and optimizing work efficiency.

[0014] 2. By using a pin, the effective length of the lifting arm can be adjusted, which improves the flexibility of the lifting arm's length during transportation and hoisting, thereby enhancing the applicability of the lifting arm.

[0015] 3. By setting an elastic washer, this utility model increases the friction on the surface of the nut block, preventing the nut block from loosening and coming off under the action of external force vibration, thereby improving the stability of the installation between the nut block and the bolt rod.

[0016] 4. By setting up the clamping plate, this utility model increases the contact area between the lifting clamp and the wall block, thereby improving the stability of the lifting clamp in holding and lifting the wall block.

[0017] 5. The universal casters in this invention facilitate the movement of the frame, improving the convenience of moving the equipment and thus enhancing the flexibility of its use.

[0018] 6. The design of this utility model facilitates the user's movement and application of force on the frame, avoiding the inconvenience of applying force when directly holding the frame for movement. Attached Figure Description

[0034] Working Principle: When using this invention, since small hoisting equipment cannot lift walls that are close to the ceiling, a 600mm*1500mm hoisting opening is first made at the bottom of the ceiling. A 200mm horizontal cut is made using a table saw, and a 300mm vertical cut is made using a water drill. After deducting the 100mm cut width from the water drill cut, a 200*200mm wall block is formed, weighing approximately 30kg. This wall block is manually moved to the gantry frame operating platform. The remaining wall is then cut with a 400mm horizontal cut using a table saw and a 500mm vertical cut using a wire saw, ultimately forming a 500mm*400mm wall block, weighing approximately 150kg. During dismantling, the template laid below the wall is removed for finished product protection. The user uses clamps 8 and bolts 9 to fix the slotted horizontal plate 7 to the top of the channel steel beam 6. Then, by pushing the frame 1... The hoisting arm 2 is moved to the outside of the partition wall. Then, the cylinder 4 is operated to move the channel steel beam 6 through the hoisting arm 2. The movement of the channel steel beam 6 causes the hoisting clamp 13 to reach the upper part of the lower side of the hoisting opening of the partition wall. Then, the pull rope 16 is released and no longer pulls on the protruding member 15, allowing the protruding member 15 to move on the surface of the guide wheel 12 and release the force on the protruding member 15. Then, the bottom of the hoisting clamp 13 is closed and abuts against the outside of the wall block. Then, the upward movement of the channel steel beam 6 causes the hoisting clamp 13 to tighten and clamp the wall block for hoisting. The guide wheel is set at the top of the hoisting clamp, and the pull rope is guided by the guide wheel. This allows the personnel on the ground to control the opening and closing of the hoisting clamp through the pull rope, so that the hoisting clamp can clamp the wall block at a high position. This improves the convenience of hoisting the wall block during demolition operations in the narrow space of the basement and optimizes the efficiency of the operation.

[0035] In summary, the hoisting equipment used for demolition work in the confined space of the basement utilizes the combination of clamping blocks 8 and bolt rods 9 to fix the slotted horizontal plate 7 to the top of the channel steel beam 6. The movement of the channel steel beam 6 then moves the hoisting clamp 13 to the top of the partition wall. The release of the pull rope 16, which no longer pulls on the protruding member 15, allows the bottom of the hoisting clamp 13 to close and abut against the outside of the wall block. The upward movement of the channel steel beam 6 then tightens the hoisting clamp 13, clamping and lifting the wall block. This achieves the goal of using guide wheels at the top of the hoisting clamp to guide the pull rope, allowing personnel on the ground to control the opening and closing of the hoisting clamp via the pull rope. This allows the hoisting clamp to hold the wall block at a high position, improving the convenience of hoisting the wall block during demolition work in the confined space of the basement and optimizing work efficiency.
