Description

Technical Field

[0001] This utility model relates to the technical field of pump pipe cleaning tools, and in particular to a concrete pump pipe cleaning tool. Background Technology

[0002] The application scenarios of concrete pump pipe devices mainly include complex or high-efficiency concrete transportation occasions such as high-rise building construction, bridge and tunnel engineering, infrastructure construction such as subways, dikes, ship locks and mining construction. They have the advantages of high efficiency, strong adaptability, saving manpower, high construction quality and flexibility and convenience, and play an important role in various construction projects.

[0003] Currently, after the pump pipe is used, it is usually necessary to clean the inside of the pump pipe in a timely manner to avoid concrete residue causing blockage. The common method is to put a cleaning ball into the pump pipe and use external pressure to make the cleaning ball move inside the pump pipe for cleaning. However, because the pressure is usually high when pressurizing, the cleaning ball has a large kinetic energy when it comes out of the pump pipe and flies a long distance, making it difficult to retrieve the cleaning ball and easy to injure people. Based on this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a concrete pump pipe cleaning tool that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A concrete pump pipe cleaning tool includes a support frame and further includes: a clamp slidably connected to the support frame; a pressure plate slidably connected inside the support frame; a cleaning ball for cleaning the inner wall of the pump pipe; the cleaning ball has a rubber layer inside, the rubber layer having a cavity; a compressed air bladder is connected between the pressure plate and the support frame; the compressed air bladder is used to inflate the cavity inside the rubber layer to change the volume of the cleaning ball; when the cleaning ball flies out of the pump pipe, the cleaning ball impacts the pressure plate, and the compressed air bladder cushions the impact of the cleaning ball.

[0007] Preferably, a bidirectional threaded rod is fixedly connected to the support frame, a nut is threadedly connected to the bidirectional threaded rod, a sliding groove is provided on the support frame, and the clamp is slidably connected to the bidirectional threaded rod and the sliding groove respectively.

[0008] Preferably, a U-shaped frame is fixedly connected to the pressure plate, and a handle is fixedly connected to the U-shaped frame.

[0009] Preferably, the compressed air bag has an air inlet and an air pipe connected to it.

[0010] Furthermore, a pin is fixedly connected to the trachea, and the pin has an air hole.

[0011] Preferably, a support tube is fixedly connected inside the cleaning ball, and the support tube is connected to the outside.

[0012] Furthermore, a tension spring is fixedly connected inside the rubber layer, and a baffle is fixedly connected to the other end of the tension spring.

[0013] Preferably, a limiting rod is fixedly connected to the support frame, and the limiting rod is slidably connected to the pressure plate.

[0014] Compared with the prior art, this utility model provides a concrete pump pipe cleaning tool, which has the following beneficial effects:

[0015] 1. This concrete pump pipe cleaning tool, by setting a clamp on the support frame, can clamp the pump pipe, thereby making the support frame act as a net to catch the cleaning balls flying out of the pump pipe, preventing the cleaning balls from flying around and injuring people and being difficult to collect.

[0016] 2. This concrete pump pipe cleaning tool uses a pressure plate to compress the air bladder when impacted, causing the air inside the air bladder to be expelled, thus buffering the impact of the cleaning ball.

[0017] 3. This concrete pump pipe cleaning tool, by setting a rubber layer in the cleaning ball to form a cavity, can change the volume of the cleaning ball by compressing the air bladder to inflate the cavity, thereby being able to handle pipes of different sizes and improving the versatility of the cleaning ball.

[0018] The parts of this device not described herein are the same as or can be implemented using existing technology. This utility model avoids the excessive impact force when the cleaning ball flies out of the pump tube, which could easily injure people and make it difficult to collect if it flies too far. At the same time, it can also provide a small amount of buffering for the impact of the cleaning ball, preventing the cleaning ball from being damaged by the impact. It can also change the volume of the cleaning ball, improving its versatility. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1: Refer to Figures 1-5 A concrete pump pipe cleaning tool includes a support frame 1 and a clamp 2 slidably connected to the support frame 1, and a pressure plate 41 slidably connected inside the support frame 1; a cleaning ball 5 for cleaning the inner wall of the pump pipe; the cleaning ball 5 has a rubber layer 51 inside, the rubber layer 51 is a cavity, and a compression air bladder 4 is connected between the pressure plate 41 and the support frame 1; the compression air bladder 4 is used to inflate the cavity inside the rubber layer 51 to change the volume of the cleaning ball 5; when the cleaning ball 5 flies out of the pump pipe, the cleaning ball 5 impacts the pressure plate 41, and the compression air bladder 4 cushions the impact of the cleaning ball 5.

[0028] In this utility model, by setting a clamp 2 on the support frame 1, the clamp 2 can clamp the pump pipe, thereby making the support frame 1 form a net bag effect, which catches the cleaning ball 5 flying out of the pump pipe and prevents the cleaning ball 5 from flying around.

[0029] When the cleaning ball 5 hits the pressure plate 41, the pressure plate 41 squeezes the air bladder 4, and the air inside the air bladder 4 is expelled outward, thereby cushioning the impact of the cleaning ball 5.

[0030] The outer material of the cleaning ball 5 is a rubber sponge with a certain absorption capacity. The cleaning ball 5 has a cavity composed of a rubber layer 51 inside, so that the user can fill the cavity with an appropriate amount of air by compressing the air bag 4 according to the size of the pump tube, so that the cleaning ball 5 can stick tightly to the inner wall of the pump tube, thereby increasing the cleaning effect of the cleaning ball 5 and increasing the versatility of the cleaning ball 5.

[0031] Example 2: Refer to Figures 1-5 Similar to Embodiment 1, but with a further improvement: a bidirectional threaded rod 21 is fixedly connected to the support frame 1, and a nut 22 is threadedly connected to the bidirectional threaded rod 21; a sliding groove 12 is provided on the support frame 1; a clamp 2 is slidably connected to the bidirectional threaded rod 21 and the sliding groove 12 respectively; a U-shaped frame 42 is fixedly connected to the pressure plate 41; a handle 43 is fixedly connected to the U-shaped frame 42; an air inlet 44 is provided on the compressed air bag 4; an air pipe 3 is connected to the compressed air bag 4; a pin 31 is fixedly connected to the air pipe 3; an air hole 311 is provided on the pin 31; a support tube 52 is fixedly connected inside the cleaning ball 5; the support tube 52 is connected to the outside; a tension spring 53 is fixedly connected inside the rubber layer 51; a baffle 54 is fixedly connected to the other end of the tension spring 53; a limit rod 11 is fixedly connected to the support frame 1; and the limit rod 11 is slidably connected to the pressure plate 41.

[0032] In this utility model, the support frame 1 is slidably connected to the clamp 2 through the sliding groove 12. The clamp 2 is slidably connected to the bidirectional threaded rod 21. By rotating the nut 22, the two clamps 2 can be squeezed to move closer to each other, thereby clamping and fixing the pump pipe.

[0033] A one-way valve is provided in the air inlet 44 so that outside air can only enter the compressed air bag 4 through the air inlet 44 in one direction. A one-way valve is provided in the air pipe 3 so that the air in the compressed air bag 4 can only flow out of the air pipe 3 to the outside in one direction.

[0034] When the ejector pin 31 is inserted into the support tube 52 on the cleaning ball 5, the ejector pin 31 lifts the baffle 54. At this time, the air inlet 44 is connected to the cavity inside the rubber layer 51. The user can pull the handle 43 to drive the pressure plate 41 to compress the air bladder 4. The air in the air bladder 4 enters the cavity inside the rubber layer 51 through the air inlet 44 to inflate it. If the cleaning ball 5 needs to be deflated, simply use the ejector pin 31 to push open the baffle 54, and the air inside the cleaning ball 5 will overflow through the support tube 52. The ejector pin 31 and the support tube 52 are interference-fitted or threaded, thus ensuring that the ejector pin 31 will not be pushed out by the gas during inflation.

[0035] The limiting rod 11 is used to limit the sliding of the pressure plate 41 on the one hand, and to block the hollow part of the support frame 1 on the other hand, so that when the support frame 1 is not in use, it can be used as a storage cage to store the cleaning ball 5 and prevent the cleaning ball 5 from sliding out of the support frame 1. When not in use, the distance between the two clamps 2 can be adjusted to the minimum, so that the cleaning ball 5 cannot slide out of the gap between the clamps 2. The support frame 1 can store multiple cleaning balls 5. Users can usually lift the entire device for carrying and moving by using the handle 43.

[0036] When using the pump, if cleaning the pump tube in the forward direction, the user can first fill the cleaning ball 5 with an appropriate amount of air and insert it into the piston tube. Then, the support frame 1 is fixed to the outlet of the pump tube by the clamp 2. Under the action of the piston pump, the cleaning ball 5 flies out from the outlet of the pump tube, and the support frame 1 catches the cleaning ball 5. If cleaning with the pump in the reverse direction, the user can first insert the cleaning ball 5 into the outlet of the pump tube and insert the ejector pin 31 into the cleaning ball 5. Then, the support frame 1 can be fixed to the pump tube by the clamp 2. By pulling the handle 43, air is filled into the cleaning ball 5 so that the cleaning ball 5 fits against the inner wall of the pump tube. The ejector pin 31 can then be pulled out, and the piston pump can be started to suck the cleaning ball 5 out of the pump tube.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
