Description

Technical Field

[0001] This application relates to the field of engineering machinery, and in particular to a pumping device for lightweight aggregate concrete. Background Technology

[0002] Lightweight aggregate concrete, also known as lightweight concrete, refers to lightweight concrete made from lightweight coarse aggregates, ordinary sand, cement, and water. It is widely used in industrial and civil buildings and other projects, and can reduce the self-weight of the structure, improve the seismic performance of the structure, save material usage, improve the efficiency of component transportation and hoisting, reduce foundation load, and improve building functions.

[0003] Existing lightweight aggregate concrete can be directly pumped to locations that require large quantities of concrete, thus saving time on the round-trip transportation of concrete. However, due to the complex environment of construction sites, scaffolding needs to be erected in advance before the pipeline can be laid, which not only delays efficiency but also occupies a lot of space. Therefore, this solution proposes a pumping device for lightweight aggregate concrete. Utility Model Content

[0004] To address the issues of scaffolding needing to be erected before pipeline laying, which delays efficiency and occupies a lot of space, this application provides a pumping device for lightweight aggregate concrete.

[0005] The pumping device for lightweight aggregate concrete provided in this application adopts the following technical solution:

[0006] A pumping device for lightweight aggregate concrete includes a concrete pump body. The output end of the concrete pump body is threadedly connected to a straight pipe. A connecting assembly is sleeved on the outer circumferential surface of the straight pipe. The connecting assembly includes a collar that is movably sleeved with the straight pipe. A horizontal shaft is fixedly passed through the collar. A support plate is movably passed through the horizontal shaft. One end of the support plate abuts against a connecting frame for positioning support and connection fixation. A positioning pin for stabilizing the connecting frame is movably passed through the lower side of one side of the connecting frame. A stud B is threadedly connected to the side of the connecting frame away from the positioning pin. One end of the stud B is rotatably connected to a clamping plate for clamping fixation.

[0007] By adopting the above technical solution, the connecting component is sleeved on the straight pipe through a collar, and is movably connected to the support plate using a horizontal shaft, so that one end of the support plate can abut against the connecting frame. The connecting frame is stabilized by a positioning pin, and then cooperates with the clamping plate with the stud B to achieve positioning support, connection fixation and clamping of the pipeline conveying part of the pumping device, ensuring the stability of the straight pipe when the concrete pump body is working.

[0008] Preferably, the inner side of the connecting frame near the positioning pin has an arc-shaped groove A, and the inner side of the clamping plate has an arc-shaped groove B.

[0009] By adopting the above technical solution, the arc-shaped groove A of the connecting frame and the arc-shaped groove B of the clamping plate are designed to better fit the outer surface of the clamped component when the clamping plate is fixed to the round pipe component under the action of the stud B, thereby increasing the contact area and improving the friction, thus enhancing the stability and reliability of the clamping and ensuring that the pipeline will not loosen or shake during the pumping of lightweight aggregate concrete.

[0010] Preferably, a horizontal plate is fixedly connected to the front of the collar, and a clamp A for horizontally fixing the support plate is symmetrically fixedly connected to the lower end of one end of the horizontal plate.

[0011] By adopting the above technical solution, the horizontal plate on the front of the collar and the clamping plate A symmetrically arranged below one end of it mainly serve to fix the support plate.

[0012] Preferably, a vertical plate is fixedly connected to one side of the bottom of the collar, and clamps B for vertically fixing the support plate are symmetrically fixedly connected to the inner side of the vertical plate.

[0013] By adopting the above technical solution, the vertical plate at the bottom of the collar and the clamping plate B symmetrically arranged on its inner side mainly serve to fix the support plate.

[0014] Preferably, a groove is provided on the lower outer side of the support plate, an extension plate is slidably connected in the groove, a connecting block is inserted into the top of the extension plate, a stud A is threadedly connected to the connecting block, a clamping block is rotatably connected to the other end of the stud A, and the end of the extension plate away from the stud A is fixedly connected to the top side of the connecting frame.

[0015] By adopting the above technical solution, the relative distance between the support plate and the connecting frame can be flexibly adjusted through the sliding cooperation of the slide groove and the extension plate to adapt to different installation and use requirements. At the same time, rotating the stud A can drive the clamping block to move, realize the stable clamping of related components, ensure the reliable connection between the connecting frame and the support plate, and thus ensure the structural stability and operational reliability of the entire pumping device during operation.

[0016] Preferably, the connecting block is threadedly connected to a stud A, and the other end of the stud A is rotatably connected to a clamping block.

[0017] By adopting the above technical solution, the position of the clamping block can be flexibly adjusted by rotating stud A to achieve stable clamping of the components, ensuring the stability and reliability of the connection of each component of the lightweight aggregate concrete pumping device.

[0018] Preferably, a rectangular groove is formed on the inner side of the support plate, and a wear-resistant layer for increasing friction is symmetrically formed in the rectangular groove. Wear-resistant plates for increasing friction are symmetrically fixedly connected to the inner side of the clamping block.

[0019] By adopting the above technical solution, the wear-resistant layer at the rectangular groove of the support plate and the wear-resistant plate on the inner side of the clamping block cooperate with each other, which can significantly increase the friction of the contact surface when clamping the component, thereby enhancing the clamping effect on the component, preventing the component from sliding or displacing during the operation of the lightweight aggregate concrete pumping device, ensuring the stability and reliability of the device connection structure, and ensuring the normal operation of the pumping work.

[0020] Preferably, the end of the straight pipe furthest from the concrete pump body is threaded with a bend, and the other end of the bend is threaded with another straight pipe.

[0021] By adopting the above technical solution, the straight pipe and the bend are connected by threads, and the two ends of the bend are connected to the straight pipe respectively. The purpose is to make the pipeline layout of the lightweight aggregate concrete pumping device more flexible, and to adjust the conveying path according to the space constraints of the actual construction site, the equipment placement, etc., to meet the conveying needs of lightweight aggregate concrete in different construction scenarios. At the same time, the threaded connection method facilitates the installation, disassembly and maintenance of the pipeline.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When the straight pipe is placed horizontally, there is no need to build scaffolding. The connecting frame can be quickly fixed by unfolding the support plate and using the positioning pin. When the straight pipe is assembled vertically upward, although simple scaffolding needs to be built, the whole installation process is simple. Turning the stud B can quickly clamp and fix the scaffolding steel pipe, avoiding the problem of spending a lot of time to build scaffolding in advance when laying pipes in the traditional way, and greatly improving the efficiency of pipe laying.

[0024] 2. The connecting components of this device are ingeniously designed. When not in use, the support plate can be locked at clamp A, reducing the overall space occupied by the device. Furthermore, when adjusting the length of the extension plate, the position of the connecting frame can be flexibly adjusted according to the actual situation, making the device more compact and adaptable to different construction environments. This effectively solves the problem of scaffolding occupying a lot of space in traditional laying methods. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0036] The device's "up, down, left, right" perspectives are... Figure 1 The orientation of the attached diagram is the reference.

[0037] This application discloses a pumping device for lightweight aggregate concrete.

[0038] Reference Figures 1-3 As shown, a pumping device for lightweight aggregate concrete includes a concrete pump body 1. A straight pipe 2 is threadedly connected to the output end of the concrete pump body 1. A connecting assembly 4 is sleeved on the outer circumferential surface of the straight pipe 2. The connecting assembly 4 includes a collar 401 that movably engages with the straight pipe 2. A circular hole is formed at the bottom of the collar 401, and a horizontal shaft 404 is fixedly inserted through the circular hole. A support plate 407 with an arc-shaped top is movably inserted through the horizontal shaft 404. One end of the support plate 407 abuts against a connecting frame 412. The bottom surface of 12 contacts the ground. The inner side of the connecting frame 412 is used to clamp and fix the steel pipe. A circular hole is opened on the lower side of one side of the connecting frame 412. A positioning pin 415 for stabilizing the connecting frame 412 is movably inserted through the circular hole. A threaded hole is opened on the side of the connecting frame 412 away from the positioning pin 415. A stud B414 is threadedly connected to the threaded hole. One end of the stud B414 is rotatably connected to a clamping plate 413. The clamping plate 413 is used to clamp and fix the scaffolding of the steel pipe assembly.

[0039] First, the end of the straight pipe 2 is threaded onto the discharge port of the concrete pump body 1. Then, by moving the collar 401, it is moved to the position of the straight pipe 2. Then, by unfolding the support plate 407, the support plate 407 is rotated vertically downward, so that the bottom of the connecting frame 412 abuts against the ground. Then, the positioning pin 415 is inserted into the connecting frame 412, thereby fixing the connecting frame 412.

[0040] When the straight pipe 2 needs to be assembled vertically upwards, a simple scaffold is installed, and then the support plate 407 is unfolded so that the connecting frame 412 can stay on the scaffold assembled with steel pipes. Then, by rotating the stud B414, the clamping plate 413 is moved to one side, so that the steel pipe is fixed between the clamping plate 413 and the connecting frame 412, thereby completing the fixing of the connecting frame 412.

[0041] Reference Figures 3-6 As shown, the connecting frame 412 has an arc-shaped groove A4120 on its inner side, located on one side of the positioning pin 415. The clamping plate 413 has an arc-shaped groove B4130 corresponding to the arc-shaped groove A4120 on its inner side. A horizontal plate 402 is fixedly connected to the front of the collar 401. A clamping plate A403 is symmetrically fixedly connected to the lower end of one end of the horizontal plate 402. The clamping plate A403 is used to horizontally fix the support plate 407. A vertical plate 405 is fixedly connected to the bottom of the collar 401 on the side below the horizontal axis 404. A clamping plate B406 is symmetrically fixedly connected to the inner side of the vertical plate 405. The clamping plate B406 is used to vertically fix the support plate 407. A vertically downward sliding groove 4070 is provided on the lower outer side of the support plate 407. An extension plate 408 is slidably connected to the top side of the connecting frame 412. A groove is provided on the outer side of the top of the extension plate 408. A connecting block 4080 is inserted into the groove. A threaded hole is provided on the side of the connecting block 4080. A stud A409 is threadedly connected to the threaded hole. The other end of the stud A409 is rotatably connected to a clamping block 410 that is slidably connected to the support plate 407. A rectangular groove is provided on the inner side of the support plate 407. A wear-resistant layer 4071 for increasing friction is symmetrically provided in the rectangular groove. A wear-resistant plate 411 for abutting against the wear-resistant layer 4071 is symmetrically fixedly connected to the inner side of the clamping block 410. A bend 3 is threadedly connected to the end of the straight pipe 2 away from the concrete pump body 1. Another straight pipe 2 is threadedly connected to the other end of the bend 3.

[0042] When the clamping plate 413 and the connecting frame 412 clamp the steel pipe, the clamping area can be increased by the action of the arc groove A4120 and the arc groove B4130, thereby improving the stability of the fixation. When the support plate 407 is not needed, the support plate 407 is locked and fixed at the clamping plate A403. When the support plate 407 needs to be used, by pulling the support plate 407, the support plate 407 is disengaged from the clamping plate A403 and locked and fixed at the clamping plate B406. When vertical installation is required, the vertical plate 413 needs to be kept in place. Above the support plate 407, when the support plate 407 is locked and fixed to the clamping plate B406, the vertical plate 405 can act as a limit. When it is necessary to adjust the length of the extension plate 408, by rotating the stud A409, the clamping block 410 can be moved inward under the action of the connecting block 4080, so that the wear-resistant plate 411 can be pressed tightly against the wear-resistant layer 4071, thereby fixing one end of the extension plate 408 and thus achieving the function of adjusting the position of the connecting frame 412.

[0043] The implementation principle of a lightweight aggregate concrete pumping device according to an embodiment of this application is as follows: During installation, the straight pipe 2 is first threadedly connected to the discharge port of the concrete pump body 1. The position of the movable collar 401 on the straight pipe 2 can be adjusted. If the straight pipe 2 is placed horizontally, the support plate 407 is unfolded so that it is vertically downward, the bottom of the connecting frame 412 abuts against the ground, and the positioning pin 415 is inserted to fix the connecting frame 412. If the straight pipe 2 is assembled vertically upward, after the scaffolding is erected, the support plate 407 is unfolded so that the connecting frame 412 is placed on the scaffolding steel pipe. The stud B414 is rotated to move the clamping plate 413. The clamping area is increased by using arc grooves A4120 and B4130 to fix the steel pipe between the clamping plate 413 and the connecting frame 412. When not in use, the support plate 407 can be locked at the clamping plate A403. When in use, it is pulled to release it and lock it at the clamping plate B406. When installed vertically, the vertical plate 405 acts as a limit. If it is necessary to adjust the length of the extension plate 408, the stud A409 is rotated to move the clamping block 410, so that the wear-resistant plate 411 is pressed against the wear-resistant layer 4071 to fix the extension plate 408, thereby realizing the adjustment of the position of the connecting frame 412 and ensuring the stability of the straight pipe 2 connection.

[0044] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
