Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a concrete pouring anti-spill device. Background Art

[0002] Concrete is an indispensable material in construction. Depending on project requirements and design standards, different grades of concrete are used. High-grade concrete has higher strength and is suitable for load-bearing structures, while low-grade concrete is often used for non-load-bearing areas. During the pouring process of high-grade and low-grade concrete, if the pump pipe moves, high-grade concrete can spill onto the low-grade concrete, causing contamination due to color differences. Therefore, a device to prevent concrete spillage during pouring has been designed. Utility Model Content

[0003] The purpose of the utility model is to provide a device for preventing concrete from spilling when pouring concrete.

[0004] The utility model is realized by the following measures: a concrete pouring anti-spill device, characterized in that it comprises a pipe clamp fixed on a pump pipe, wherein the outer wall of the pipe clamp is symmetrically provided with bosses, the bosses are fixedly provided with studs, and the studs are provided with adjusting rods and fixed by nuts;

[0005] The adjusting rod comprises an upper rod and a lower rod, the upper rod and the lower rod are connected by a telescopic rod, the outer rod of the telescopic rod is fixed to the outer wall of the lower end of the upper rod, the inner rod of the telescopic rod is fixed to the outer wall of the upper end of the lower rod, the upper end of the inner rod extends into the outer rod, the upper end surface of the inner rod and the top wall of the outer rod are connected by a spring, the upper end of the upper rod is sleeved on the stud, and the lower ends of the two lower rods are connected by a bottom plate that blocks the pump pipe outlet;

[0006] A pull ring is provided below the bottom plate. The pull ring can be fixed to the bottom plate or rotatably provided on the bottom plate via a hinge.

[0007] The outer end surface of the boss is flat, which facilitates the fixing of the adjusting rod.

[0008] A limiting opening is opened on the upper portion of the inner rod, and a screw rod is provided through the outer rod via a threaded connection, and the screw rod can pass through the limiting opening.

[0009] The outer wall of the screw can be in close contact with the top wall of the limiting opening.

[0010] An annular baffle is fixedly arranged on the outer edge of the bottom plate.

[0011] A threaded sleeve that matches the screw rod is fixedly arranged on the outer wall of the outer sleeve, and the outer end of one threaded sleeve is sealed.

[0012] The pipe clamp includes two semicircular ring plates, both ends of which are fixed by bolt connection, and each of the semicircular ring plates is provided with the adjusting rod.

[0013] A handle is welded on the outer end of the screw.

[0014] How to use:

[0015] Place the bottom plate on the pump pipe opening, and then fix the pipe clamp on the appropriate position of the pump pipe. At this time, the bottom plate can seal the pump pipe opening under the action of the spring;

[0016] When the pump tube needs to be opened, the nut fixing the adjusting rod is loosened, the pull ring is pulled to stretch the spring, and the adjusting rod is rotated to screw the bottom plate out of the pump tube; when the pump tube opening needs to be sealed again, the pull ring is pulled to stretch the spring, and the adjusting rod is rotated to screw the bottom plate into the bottom of the pump tube opening, and the pull ring is released to seal it by the spring tension.

[0017] In addition, after long-term use, the spring tension may be insufficient. Therefore, the screw and the stopper are provided. When the spring needs to be stretched, the screw can be rotated to rotate it out of the stopper. At this time, the spring can be stretched under the action of the tension, which makes it easier to screw the bottom plate out and screw it into the bottom of the pump nozzle. When the spring is reset, the screw is rotated to enter the stopper. At this time, the inner rod cannot move along the outer rod, and the spring cannot be stretched. In this case, even if the spring tension is insufficient, the bottom plate still has a good sealing effect.

[0018] Due to the presence of the spring and the telescopic rod, the bottom plate can be spaced apart from the pump nozzle during the rotation process, so the provision of the annular baffle can further enhance the blocking effect.

[0019] The beneficial effects brought about by the technical solution provided by the embodiment of the utility model are: providing a concrete pouring anti-spill device with a simple overall structure and easy use; the cooperation of the spring and the telescopic rod facilitates the screwing of the bottom plate into and out of the pump pipe mouth; the cooperation of the screw rod and the limit port can limit the inner rod when sealing the pump pipe mouth, preventing the spring from displacement, thereby ensuring the sealing effect.

[0029] The adjusting rod 3 includes an upper rod 301 and a lower rod 302, which are connected by a telescopic rod. The outer rod 303 of the telescopic rod is fixed to the outer wall of the lower end of the upper rod 301, and the inner rod 304 of the telescopic rod is fixed to the outer wall of the upper end of the lower rod 302. The upper end of the inner rod 304 extends into the outer rod 303. The upper end surface of the inner rod 304 is connected to the top wall of the outer rod 303 by a spring 8. The upper end of the upper rod 301 is sleeved on the stud 102, and the lower ends of the two lower rods 302 are connected by a bottom plate 5 that blocks the outlet of the pump pipe 11.

[0030] A pull ring 501 is provided below the bottom plate 5 . The pull ring 501 can be fixed on the bottom plate 5 or can be rotatably provided on the bottom plate 5 via a hinge.

[0031] The outer end surface of the boss 101 is flat, which facilitates the fixation of the adjusting rod 3 .

[0032] A limiting opening 30401 is opened at the upper portion of the inner rod 304 , and a screw rod 9 is provided through the outer rod 303 via a threaded connection, and the screw rod 9 can pass through the limiting opening 30401 .

[0033] The outer wall of the screw rod 9 can be in close contact with the top wall of the limiting opening 30401 .

[0034] An annular baffle 6 is fixedly provided on the outer edge of the bottom plate 5 .

[0035] A threaded sleeve 10 that cooperates with the screw 9 is fixedly provided on the outer wall of the outer rod 303, and the outer end of one threaded sleeve 10 is sealed.

[0036] The pipe clamp 1 comprises two semicircular ring plates, both ends of which are connected and fixed by bolts 2 , and an adjusting rod 3 is provided on each semicircular ring plate.

[0037] A handle 4 is welded to the outer end of the screw rod 9 .

[0038] How to use:

[0039] Seal the bottom plate 5 on the opening of the pump tube 11, and then fix the tube clamp 1 on the appropriate position of the pump tube 11. At this time, the bottom plate 5 can seal the opening of the pump tube 11 under the action of the spring 8;

[0040] When the pump tube 11 needs to be opened, the nut 7 fixing the adjusting rod 3 is loosened, the pull ring 501 is pulled to stretch the spring 8, and the adjusting rod 3 is rotated to screw the bottom plate 5 out of the pump tube 11; when the pump tube 11 port needs to be sealed again, the pull ring 501 is pulled to stretch the spring 8, and the adjusting rod 3 is rotated to screw the bottom plate 5 into the bottom of the pump tube 11 port, and the pull ring 501 is released to seal it with the tension of the spring 8.
