Description

Technical Field

[0001] The utility model relates to the technical field of installation of wedge-shaped anti-falling beams, in particular to a pre-buried barrel dismantling device for installation of wedge-shaped anti-falling beams. Background Art

[0002] When installing the non-embedded steel tube of the tenon-shaped anti-fall beam, an oblong reserved hole must be set on the top of the pier in advance. The non-embedded steel tube must be placed in the reserved hole and its position must be adjusted so that it is aligned with the extended steel tube embedded at the bottom of the beam to facilitate the subsequent installation of the remaining components of the anti-fall beam.

[0003] The reserved holes on the pier top are generally formed by pre-embedding a barrel with an oblong cross-section at the corresponding position of the pier top before the pier is cast. The pre-embedded barrel is removed after the pier has initially set. Since the concrete has a strong grip on the barrel after initial setting, it is more difficult for construction workers to pull out the pre-embedded barrel, and often requires the cooperation of multiple people, which is inconvenient to operate.

[0004] To this end, the present application specifically proposes a pre-buried barrel removal device for installing a wedge-shaped anti-fall beam to solve the above technical problems. Utility Model Content

[0005] The main purpose of the utility model is to solve the above-mentioned deficiencies and provide a pre-buried barrel removal device for installing a wedge-shaped anti-fall beam, with the help of which construction workers can more easily pull out the pre-buried barrel on the pier top from the initial setting concrete.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A pre-buried barrel dismantling device for installing a wedge-shaped anti-fall beam comprises: two bases symmetrically placed on a working platform on a pier top, with brackets fixedly provided on the bases; a sliding rod erected between the two brackets and located above the barrel to be dismantled; a sliding mounting frame slidably provided on the sliding rod; a lifting assembly fixedly provided on the sliding mounting frame; and a supporting assembly provided at the lifting end of the lifting assembly for supporting the inner cavity of the barrel to be dismantled.

[0008] Furthermore, the supporting assembly includes a scissor jack, a pressure block fixedly arranged at the supporting ends on both sides of the scissor jack, a frame fixedly arranged at the top of the scissor jack, and a lifting lug fixedly arranged at the top of the frame.

[0009] Furthermore, the pressing block is in an arc shape that completely fits the arc-shaped inner wall of the barrel to be disassembled, and a rubber pad with uniform thickness is fixedly provided on the outer wall of the pressing block.

[0010] Furthermore, the sliding mounting frame includes a shell arranged below the slide rod, a rotating support fixedly arranged on the top of the shell, and a guide wheel rotatably arranged on the rotating support and located above the slide rod, and the bottom of the guide wheel abuts the top of the slide rod.

[0011] Furthermore, the lifting assembly includes a drum rotatably arranged in the shell and parallel to the sliding rod, a steel wire rope with one end fixed on the drum and the other end tied to the lifting ear, and a reduction motor fixed on the shell and with the output shaft transmission connected to the drum rotating shaft.

[0012] Furthermore, a universal wheel with a brake is provided at the bottom of the base.

[0013] The beneficial effects of the present invention are as follows:

[0014] The utility model provides a base, a bracket, a sliding rod, a sliding mounting frame, a lifting assembly and a top support assembly on a working platform, and the sliding mounting frame slides along the sliding rod, driving the lifting assembly and the top support assembly to move together along the direction of the sliding rod until the top support assembly is located just above the barrel to be disassembled, and then the lifting assembly is used to lower the top support assembly to the inner cavity of the barrel to be disassembled, and then the top support assembly is opened to support the inner wall of the barrel to be disassembled, and finally the lifting assembly is used to drive the top support assembly to rise, and the top support assembly is driven to rise together with the inner wall of the barrel to be disassembled by the static friction between the top support assembly and the inner wall of the barrel to be disassembled, so that the barrel to be disassembled is pulled out of the initial setting concrete;

[0015] By setting the supporting assembly as a combination of a scissor jack and an arc-shaped top pressure block, the top pressure block can be tightened against the inner wall of the barrel to be dismantled by simply turning the adjusting screw of the scissor jack manually, so that the barrel to be dismantled can be pulled out of the concrete by utilizing the friction between the top pressure block and the inner wall of the barrel to be dismantled.

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] like Figure 1-4 As shown, the utility model provides a pre-buried barrel dismantling device for installing a wedge-shaped anti-fall beam, comprising:

[0024] Two bases 1 are symmetrically placed on the working platform 2 on the top of the pier, and a bracket 3 is fixed on the base 1;

[0025] The sliding rod 4 is mounted between the two brackets 3 and is located above the barrel 5 to be disassembled;

[0026] A sliding mounting frame 6 is slidably arranged on the slide rod 4;

[0027] A lifting assembly 7 is fixedly mounted on the sliding mounting frame 6;

[0028] The supporting assembly 8 is provided at the lifting end of the lifting assembly 7 and is used to support the inner cavity of the barrel body 5 to be disassembled.

[0029] When in use, the sliding mounting frame 6 is slid along the slide rod 4, driving the lifting assembly 7 and the supporting assembly 8 to move along the direction of the slide rod 4 until the supporting assembly 8 is located directly above the barrel body 5 to be disassembled, and then the lifting assembly 7 is used to lower the supporting assembly 8 to the inner cavity of the barrel body 5 to be disassembled, and then the supporting assembly 8 is opened to support the inner wall of the barrel body 5 to be disassembled, and finally the lifting assembly 7 is used to drive the supporting assembly 8 to rise, and the supporting assembly 8 is driven to rise together with the static friction between the inner wall of the barrel body 5 to be disassembled, thereby pulling the barrel body 5 to be disassembled out of the initial setting concrete.

[0030] In one embodiment, the supporting assembly 8 includes a scissor jack 81, a pressure block 82 fixedly provided at the supporting ends on both sides of the scissor jack 81, a frame 83 fixedly provided at the top of the scissor jack 81, and a lifting lug 84 fixedly provided at the top of the frame 83.

[0031] With this design, the top pressure block 82 can be extended outward and tightened to the inner cavity of the barrel body 5 to be removed by manually rotating the adjusting screw of the scissor jack 81, and the setting of the frame 83 provides an operating space for the user to rotate the adjusting screw of the scissor jack 81.

[0032] In one embodiment, the pressing block 82 is in an arc shape that completely fits the arc-shaped inner wall of the barrel body 5 to be disassembled, and a rubber pad 9 with uniform thickness is fixedly provided on the outer wall of the pressing block 82 .

[0033] This design improves the static friction coefficient between the top pressure block 82 and the barrel body 5 to be disassembled, and reduces the possibility of the barrel body 5 to be disassembled slipping during the lifting process.

[0034] In one embodiment, the sliding mounting frame 6 includes a shell 61 arranged below the slide rod 4, a rotating support 62 fixedly arranged on the top of the shell 61, and a guide wheel 63 rotatably arranged on the rotating support 62 and located above the slide rod 4, and the bottom of the guide wheel 63 abuts the top of the slide rod 4.

[0035] With this design, applying a certain external force to the sliding mounting frame 6 along the direction of the slide rod 4 can drive the guide wheel 63 to roll on the slide rod 4, and then drive the housing 61 to move along the direction of the slide rod 4.

[0036] In one embodiment, the lifting assembly 7 includes a drum 71 rotatably arranged in the shell 61 and parallel to the slide rod 4, a steel wire rope 72 with one end fixed on the drum 71 and the other end tied to the lifting ear 84, and a reduction motor 73 fixed on the shell 61 and with the output shaft transmission connected to the rotating shaft of the drum 71.

[0038] In one embodiment, a universal wheel 10 with a brake is provided at the bottom of the base 1 .

[0039] With this design, the base 1 can be moved by the universal wheels 10 to the corresponding position of the other barrel bodies 5 to be removed on the pier top.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.

[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0042] In addition, "multiple" means more than two. Furthermore, the technical solutions of the various embodiments may be combined with each other, but this must be based on the premise that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is mutually inconsistent or cannot be implemented, it shall be deemed that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
