Description

Technical Field

[0001] The utility model relates to the field of bored cast-in-place pile foundation construction, in particular to a convenient reverse hoisting device for the steel cage of a pile foundation. Background Technique

[0002] In the construction of bored cast-in-place pile foundations, in order to fix the steel cage during the pouring process and make its plane position and elevation at the designed position, a corresponding reverse hoisting device needs to be set up to hoist and fix the steel cage. The traditional reverse hoisting device generally adopts the method of welding the reverse hoisting steel bars to the construction steel casing or the orifice crosspiece beam to reversely hoist and fix the steel cage. On the one hand, the connection operation is time-consuming and easily damages the steel casing. On the other hand, it is easy to cause uneven stress on each hoisting bar and reduce the installation accuracy of the steel cage;

[0003] In this regard, the Chinese invention patent with the authorization announcement number CN117142311A discloses a steel cage hoisting device and its hoisting method, which solves the problem that the steel cage is prone to tilt and shake, and the position of the steel cage needs to be adjusted repeatedly. However, the volume and weight of the steel cage are large, and the actual adjustment is inconvenient. It includes a hoisting seat, a positioning ring is arranged below the hoisting seat, two positioning columns are fixedly connected to the top of the positioning ring, two first positioning holes are opened on the hoisting seat, and the positioning columns penetrate through the first positioning holes. The top of the positioning column is fixedly connected with a first guiding column, and the first guiding column is of a frustum-shaped structure. Two movable seats are arranged above the hoisting seat, and the movable seats and the positioning columns are connected through elastic friction members. An activity ring is arranged on the top of the hoisting seat, and the movable seats and the activity ring are connected through a reverse meshing structure; reducing the possibility of the steel cage tilting and shaking during the process of being lowered into the foundation pit, and increasing the stability;

[0004] The inner positioning components of the existing reverse hoisting device cannot be adjusted according to the size specifications of the steel cage of the pile foundation, with poor flexibility, inconvenient adjustment, low practicability, and reduced universality. Moreover, it cannot hoist the steel cage of the pile foundation smoothly. For this reason, we propose a convenient reverse hoisting device for the steel cage of the pile foundation to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a convenient reverse hoisting device for the steel cage of a pile foundation to solve the problems raised in the above background technique.

[0006] A convenient reverse hoisting device for the steel cage of a pile foundation includes support channel steels. The support channel steels are symmetrically arranged in pairs as a group, and there are two groups of support channel steels. The two groups of support channel steels are connected by a support plate, and two groups of support plates are symmetrically arranged;

[0007] The bottom wall of the supporting channel steel is fixedly connected with a supporting sleeper. An adjusting assembly is arranged between the supporting channel steels. The adjusting assembly is internally provided with a positive and negative screw rod, a handle, a sliding seat, a sliding block and a sliding groove. One side end of the positive and negative screw rod is movably connected to the inner wall of the supporting plate through a bearing, and the other side end of the positive and negative screw rod movably penetrates through the second supporting plate and extends outwards. A handle is fixedly connected to the side end of the positive and negative screw rod. A sliding seat is movably connected to the positive and negative screw rod, and two groups of sliding seats are symmetrically arranged about the midpoint of the positive and negative screw rod;

[0008] Anchor pad steel plates are fixedly connected to the top and bottom walls of the sliding seat. The anchor pad steel plates are arranged parallel to the supporting channel steel. A fastening sleeve is fixedly connected to the bottom wall of the anchor pad steel plate. A reverse suspension steel bar is movably connected to the middle of the bottom of the fastening sleeve.

[0009] Preferably, an anti-slip pad is fixedly connected to the outer wall of the handle.

[0010] Preferably, two groups of supporting sleepers are symmetrically arranged about the midpoint of the supporting channel steel.

[0011] Preferably, a buffer pad is fixedly connected to the bottom wall of the supporting sleeper.

[0012] Preferably, sliding blocks are symmetrically and fixedly connected to both side walls of the sliding seat. Sliding grooves are formed in the opposite side walls of the supporting channel steel, and the sliding blocks are movably clamped in the sliding grooves.

[0013] Preferably, internal threads are arranged on the inner wall of the fastening sleeve, external threads are arranged on the outer wall of the reverse suspension steel bar, and the external threads are movably meshed with the internal threads.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model is provided with a supporting sleeper for being conveniently padded on the bottom wall of the reinforcement cage, so as to better support the bottom wall of the reinforcement cage. By arranging a buffer pad, it is convenient to protect the bottom wall of the reinforcement cage and avoid the reinforcement cage directly bumping against the supporting sleeper, thereby protecting the supporting sleeper and prolonging its service life. By arranging an adjusting component, it is convenient to adjust the spacing distance of the anchor pad steel plates, so as to adjust the positions of multiple groups of inverted suspension steel bars. The user rotates the handle, and the handle drives the positive and negative screw rod to rotate. The rotation of the positive and negative screw rod drives the sliding seats to approach each other, and the sliding seats drive the anchor pad steel plates to displace, so as to move the inverted suspension steel bars, so as to better fit the inner wall of the reinforcement cage, making the inverted suspension more firm. By arranging a sliding block in cooperation with a sliding groove, the sliding seat moves linearly with stronger stability. By arranging a fastening sleeve, the internal thread is used in cooperation with the external thread of the inverted suspension steel bar, which is convenient for the inverted suspension steel bar to be disassembled and assembled in the fastening sleeve. The structure is simple, time-saving and labor-saving. By connecting the top end of the inverted suspension steel bar with a fastening sleeve and arranging an anchor pad steel plate, when the welding of the bottom end of the suspension bar and the main reinforcement of the reinforcement cage is completed, through the connection length of the fastening sleeve and the plane position of the inverted suspension steel bar on the channel steel bracket, the forces of each inverted suspension steel bar are further balanced and the positioning accuracy of the reinforcement cage is strengthened. At the same time, the stability is higher and the installation and disassembly are more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
