Description

Technical Field

[0001] The utility model relates to the technical field of multi-warehouse pipe gallery structure construction in municipal road construction, in particular to a concrete unloading device in the process of pouring a pipe gallery main body. Background Art

[0002] At present, during the construction of urban roads, when pouring concrete in multi-bin structures such as power trenches and integrated pipe corridors, pump trucks are often used to directly pump concrete into the structural walls, and workers then use inserted vibrators to vibrate the concrete to make it flow into the structural bottom plate. During the pouring process, due to unstable pump pipes and improper operation of workers, concrete can easily spill on the top plate or cause concrete waste. In addition, if the concrete scattered on the top plate is not handled in time, once the initial setting time of the concrete is exceeded, it is easy to form cold joints with the subsequent concrete when pouring continues. Later, under the influence of various media such as external water, it will have an adverse effect on the structural steel bars and cause damage to the structure. Therefore, in order to ensure the integrity and continuity of the structural concrete and ensure the tightness of the structure between the middle partition wall and the top plate, combined with the actual conditions of on-site construction, a mobile and assembleable concrete unloading device is developed and used to avoid the occurrence of the above problems in application, achieving the purpose of saving labor and material costs and ensuring a reliable and beautiful structure.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A mobile and assembleable concrete unloading device comprises a unloading chute, wherein the unloading chute comprises an upper chute body and a lower chute body, and the unloading chute is assembled from four plates through a mortise and tenon structure; the unloading chute also comprises a guide rail and a guide wheel slidably connected to the guide rail, the bottom surface of the guide rail adopts an inner concave surface embedded with the surface layer steel bars, the guide wheel is installed at the bottom of a supporting leg, a threaded hole is arranged on the supporting leg, the threaded hole horizontally penetrates the supporting leg, a screw rod is inserted into two corresponding threaded holes on the left and right, and the supporting leg is welded to the bottom surface of the lower chute body.

[0006] As a further solution of the utility model: the diameter of the threaded hole is 0.5 cm.

[0007] As a further solution of the utility model: the length of the screw rod is 0.5 meters.

[0008] As a further solution of the utility model: a handheld telescopic rod is installed between the two side walls of the lower tank body.

[0009] Compared with the prior art, the beneficial effects of the utility model are: 1. The unloading device can effectively solve the construction cold joints formed between the wall and the top plate due to the concrete exceeding the initial setting time when pouring concrete, and ensure the integrity of the structure. 2. The unloading chute adopts a lightweight and high-strength aluminum alloy mortise and tenon structure to ensure safety and stability during the unloading process, while facilitating manual control. 3. The opening size of the unloading bottom plate is controlled by the cooperation of the support legs and the screw rod, which can effectively control the pouring speed and pouring amount. 4. The use of an assembleable structural structure is convenient for workers to assemble and disassemble, which is conducive to greatly saving labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0015] See also Figure 1-3 The utility model provides a mobile and assembleable concrete unloading device, the structure of which includes a unloading chute, the unloading chute includes an upper chute body 2 and a lower chute body 3, and the unloading chute is assembled by four assembleable high-strength and light-weight aluminum alloy plates through a mortise and tenon structure.

[0016] It also includes a guide rail 5 and a guide wheel 7 slidably connected to the guide rail 5. In order to achieve the convenience during concrete pouring and the purpose of rapid unloading of the entire device, the guide rail 5 is made of high-strength and lightweight aluminum alloy material. The bottom surface of the guide rail 5 adopts an inner concave surface that is embedded with the surface steel bars, and the guide rail 5 is an internal hollow thin-walled structure. The inner concave surface should be flat and smooth, and fit closely with the surface steel bars to ensure that the guide wheel 7 does not deviate or derail during the forward process. The guide wheel 7 is made of solid rubber material, which has high strength, good toughness, is not easy to deform, and has high stability.

[0017] The guide wheel 7 is installed at the bottom of the support leg 4, and a threaded hole with a diameter of 0.5 cm is set on the support leg 4, and the threaded hole horizontally penetrates the support leg 4. A screw rod 6 with a length of 0.5 meters is inserted into the two corresponding threaded holes on the left and right, and the support leg 4 is welded to the bottom surface of the lower tank body 3. The purpose of controlling the spacing of the support legs 4 is achieved by screwing the screw rod 6 into and out of the threaded hole, thereby controlling the size of the opening on the bottom surface of the lower tank body 3, thereby effectively controlling the discharge speed and discharge amount.

[0018] A hand-held telescopic rod 1 is installed between the two side walls of the lower tank body 3. The hand-held telescopic rod 1 can be fixed on the lower tank body 3 by a nut. The hand-held telescopic rod 1 is extended and retracted laterally along with the discharge of the bottom opening of the lower tank body 3. The worker can control the entire unloading device to run along the guide rail 5 through the hand-held telescopic rod 1.

[0019] The specific method of use is as follows: first, lay the guide rails 5 on both sides of the middle partition wall of the pipe gallery structure, and stably fix the guide rails 5 on the surface steel bars. Then, assemble the upper tank body 2 and the lower tank body 3, install the handheld telescopic rod 1 on the lower tank body 3, and finally insert the screw rod 6 into the support leg 4 through the threaded hole on the support leg 4. After the overall unloading device is assembled, it can be manually erected on the guide rails 5.

[0020] The preferred implementation modes of the present application are described in detail above, but the present application is not limited to the above implementation modes, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present application.
