Description

Technical Field

[0001] This application relates to the field of steel cage installation equipment, and in particular to a device for lowering steel cages for dry-work bored piles. Background Technology

[0002] In the construction industry, it is often necessary to excavate holes in the ground and install vertical piles within them. Construction workers need to lower a reinforcing cage into the pit, then inject cement mortar into the pit to solidify and form a reinforced concrete pile. Currently, the lowering of the reinforcing cage is done using a crane, which lifts the cage and places it inside. When using a crane, construction workers need to clear the site to provide ample space for the crane to move, and the area above the pit needs to be cleared for crane operation. Therefore, a well-planned sequence of high-altitude operations and hoisting work is essential.

[0003] The aforementioned technical solutions have the following drawbacks: at the construction site, when the construction space is small or there is a building structure above the foundation pit that obstructs the view, it is difficult to use a crane to lift the steel cage, causing inconvenience to the construction. Utility Model Content

[0004] To facilitate the lowering of steel reinforcement cages in locations where cranes are inconvenient for construction workers, this application provides a device for lowering steel reinforcement cages for dry-work bored piles.

[0005] The present application provides a dry-work bored pile reinforcement cage lowering device with the following technical solution:

[0006] A device for lowering a steel cage for a dry-worked bored pile includes a crossbar, multiple supports, pulleys, and ropes. The pulleys are rotatably connected to the crossbar, the supports are installed at both ends of the crossbar and are used to support the crossbar in a horizontal suspension, and the ropes are set on the pulleys. One end of the rope is fixed to the crossbar, and the other end is hung on the pulley and connected to a traction device.

[0007] By adopting the above technical solution, brackets are set at both ends of the crossbar, allowing the brackets to be placed on the ground and support the crossbar. This allows the pulley to be suspended and rotate on the crossbar. The user sets the bracket at the pit opening and sets a rope on the pulley, which can be looped onto the reinforcing cage. By controlling the movement of the rope end, the user can make the rope suspend the reinforcing cage and move it vertically. By setting multiple lowering devices along the circumference of the reinforcing cage, the effect of hoisting the reinforcing cage can be achieved, and the reinforcing cage can be lowered in places where it is inconvenient to use a crane.

[0008] Optionally, the pulleys are configured in multiple ways, with a rope mounted on each pulley.

[0009] By adopting the above technical solution, multiple pulleys are set on the crossbar, and a rope is set on each pulley, so that multiple ropes can be looped on the steel cage and hoisted, thereby reducing the stress on the ropes and reducing the probability of rope breakage.

[0010] Optionally, the ends of the ropes are provided with connectors, and multiple rope ends are fixed to the same connector, with a traction rope fixed to the connector.

[0011] By adopting the above technical solution, and by setting connectors at the ends of the ropes, multiple ropes can be connected. By controlling the traction equipment to pull the traction rope, the connectors can move multiple ropes, thus facilitating the vertical movement of the steel cage by construction workers.

[0012] Optionally, a number of partitions are fixed on the crossbar, and the partitions are arranged between two adjacent pulleys.

[0013] By adopting the above technical solution, by setting a partition on the crossbar, the partition separates two adjacent pulleys, thereby separating the ropes on the two pulleys from each other and reducing the probability of the two ropes coming into contact and getting tangled.

[0014] Optionally, the pulley has a groove, and the rope is secured in the groove.

[0015] By adopting the above technical solution, grooves are made on the pulley, allowing the rope to be locked in the grooves, thereby reducing the chance of the rope slipping off the pulley and enabling the rope to move stably while locked on the pulley.

[0016] Optionally, the bracket and the crossbar are detachably connected.

[0017] By adopting the above technical solution, and by making the bracket and the crossbar detachable, users can install brackets of different sizes on the crossbar, which makes it convenient for construction workers to hoist the steel cage into foundation pits of different sizes.

[0018] Optionally, the bracket is provided with a base plate for placing on the ground, and an anti-slip layer is provided on the bottom surface of the base plate. The anti-slip layer is made of rubber with a rough surface.

[0019] By adopting the above technical solution, a base plate is installed on the support, which makes the base plate contact the ground, thereby increasing the contact area between the base plate and the ground and increasing the friction. By installing an anti-slip layer on the base plate, the friction between the base plate and the ground is further increased, reducing the chance of the base plate slipping on the ground and improving the stability of the pulley hoisting of the steel cage.

[0020] Optionally, the base plate is provided with multiple bolts, which penetrate the base plate and are detachably connected to the ground.

[0021] By adopting the above technical solution, bolts are installed on the base plate to fix it to the ground, thereby improving the connection stability of the base plate on the ground and reducing the probability of the base plate slipping on the ground.

[0022] In summary, the beneficial technical effects of this application are as follows:

[0023] 1. By setting supports at both ends of the crossbar, the supports can be placed on the ground and support the crossbar, so that the pulley can be suspended and rotate on the crossbar. The user sets the support at the pit opening and sets the rope on the pulley, so that the rope can be looped on the steel cage. The user can control the movement of the rope end to make the rope suspend the steel cage and move it vertically. By setting multiple lowering devices on the steel cage along the circumference, the effect of hoisting the steel cage can be achieved, and the steel cage can be lowered in places where it is inconvenient to use a crane.

[0024] 2. By setting multiple pulleys on the crossbar and a rope on each pulley, multiple ropes can be looped onto the steel cage and used to hoist the steel cage, thereby reducing the stress on the ropes and the probability of rope breakage.

[0025] 3. By setting a base plate on the support, the base plate is brought into contact with the ground, increasing the contact area between the base plate and the ground and improving friction. By setting an anti-slip layer on the base plate, the friction between the base plate and the ground is further improved, reducing the chance of the base plate slipping on the ground and improving the stability of the pulley hoisting of the steel cage.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a device for lowering the reinforcing cage of a dry-work bored pile, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a crossbar 1, multiple supports 2, pulleys 3, and ropes 4. The pulleys 3 are rotatably connected to the crossbar 1 and are coaxially connected to the crossbar 1. The supports 2 are located at both ends of the crossbar 1 and are used to support the crossbar 1 so that the crossbar 1 can be horizontally placed on the ground. The ropes 4 are hung on the pulleys 3. One end of the ropes 4 is fixed to the crossbar 1, and the other end is connected to the traction equipment. The user welds and fixes the lifting point steel pipe 6 to the steel cage so that the lifting point steel pipe 6 is horizontally placed. The user can then loop the ropes 4 onto the lifting point steel pipe 6. The user can control the movement of the ropes 4 through the traction equipment, so that the steel cage can be lowered into the foundation pit through the ropes 4.

[0034] Reference Figure 4 Multiple pulleys 3 are provided, and each pulley 3 is equipped with a rope 4. In this embodiment, the number of pulleys 3 is set to three. A groove 31 is provided on the pulley 3. The groove 31 is an annular groove. The rope 4 is engaged in the groove 31, thereby reducing the probability of the rope 4 slipping on the pulley 3 and becoming disconnected from the pulley 3.

[0035] Reference Figure 3 The ends of the ropes 4 are provided with connectors 41. Multiple ropes 4 are of the same length and the ends of the ropes 4 are fixed to the same connector 41. A traction rope 42 is fixed to the connector 41. By using a traction device to pull the traction rope 42, the user can control the simultaneous movement of multiple ropes 4, thereby facilitating the vertical movement of the steel cage.

[0036] Reference Figure 4 A partition 5 is provided between two adjacent pulleys 3. The partition 5 is fixed to the bracket 2. The partition 5 is used to separate two adjacent ropes 4, thereby reducing the probability of the ropes 4 contacting each other when moving and reducing the probability of the ropes 4 getting tangled. The end of the rope 4 can be fixed to the partition 5. The user can lift the steel cage by pulling the other end of the rope 4.

[0037] Reference Figure 4 and Figure 5The bracket 2 and the crossbar 1 are detachably connected. A horizontal tube 21 is installed on the bracket 2. The horizontal tube 21 is horizontally positioned, and an insertion hole 211 is opened at one end of the horizontal tube 21. The end of the crossbar 1 can be inserted into the insertion hole 211, thus allowing the bracket 2 to support the crossbar 1 in mid-air. By installing brackets 2 of different shapes on the crossbar 1, users can position the crossbar 1 outside pits of different diameters. A base plate 22 is installed at the bottom of the bracket 2, and the base plate 22 is fixedly connected to the bracket 2. The base plate 22 is used for horizontal placement on the ground. An anti-slip layer is adhered to the bottom surface of the base plate 22. The anti-slip layer is made of a rough-surfaced rubber material, which increases the friction between the base plate 22 and the ground, reducing the chance of the bracket 2 slipping on the ground.

[0038] Reference Figure 5 The base plate 22 has multiple through holes, and bolts 23 are installed in the through holes. The bolts 23 are perpendicular to the base plate 22. The bolts 23 are inserted into the through holes and fixed to the ground, which can further improve the connection strength between the base plate 22 and the ground and reduce the chance of the bracket 2 slipping.

[0039] The implementation principle of this application embodiment is as follows: by setting a bracket 2 on the crossbar 1, the pulley 3 can be suspended and rotated outside the foundation pit. By setting a rope 4 on the pulley 3, one end of the rope 4 is fixed to the partition plate 5, and the other end is connected to the traction device. By looping the rope 4 on the lifting point steel pipe 6 of the steel cage, the user controls the raising and lowering of the rope 4, which enables the steel cage to move vertically in the foundation pit, thereby achieving the effect of lowering the steel cage.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
