Description

Technical Field

[0001] The invention relates to the technical field of concrete pumping, and in particular to a material level sensing equipment bracket, a material level sensing mechanism and a concrete pumping machine. Background Art

[0002] The concrete level sensing of concrete pumping machinery depends on the level meter. For the rod-type level meter, it is necessary to install a bracket near the hopper, which is used to clamp the rod-type level meter. Usually, the bracket of the rod-type level meter is directly welded to the inner side of the hopper arm, and the rod-type level meter is inserted into the bracket from above. After adjusting the height, it is tightened with bolts. The problems with this bracket are: 1. The bracket is directly fixed to the inner wall of the hopper by welding, and the position is difficult to adjust and difficult to replace if damaged; 2. The bracket is often located in a deeper position in the hopper, which is easy to pour concrete, causing the concrete to solidify and difficult to clean; 3. When the position of the bracket is close to the probe of the level meter and is easily poured by wet concrete, it will cause the level signal to be transmitted incorrectly, resulting in inaccurate level detection; 4. When the bracket cannot be disassembled, it will make daily cleaning difficult, and the concrete is difficult to clean. The accumulated dry concrete will wrap the bracket and the level meter, eventually causing the level meter to fail. Summary of the invention

[0003] The purpose of the present invention is to overcome the problems existing in the prior art and to provide a material level sensing equipment bracket, a material level sensing mechanism and a concrete pumping machine. The material level sensing equipment bracket is quick and convenient to disassemble and assemble, is not easily bonded by concrete, effectively reduces the generation of material level error signals, and improves the accuracy of material level detection.

[0004] In order to achieve the above-mentioned objectives, the present invention provides, on one hand, a material level sensing device bracket, the material level sensing device bracket comprising a first frame body and a second frame body, the first frame body and the second frame body being hingedly connected to each other, and the material level sensing device bracket being configured to be convertible between an open state and a folded state; in the open state, the first frame body and the second frame body can respectively abut against a screen frame of a concrete pumping machine to prevent the material level sensing device bracket from falling from the screen frame, and in the folded state, the first frame body and the second frame body can respectively detach from the screen frame to allow the material level sensing device bracket to detach from the screen frame; wherein, the first frame body and / or the second frame body are used for installing a material level sensing device.

[0005] Optionally, in the open state, the angle between the first frame and the second frame is 180°, and in the folded state, the angle between the first frame and the second frame is an obtuse angle.

[0006] Optionally, the first frame includes a first hook capable of hooking the screen frame, the second frame includes a second hook capable of hooking the screen frame, and the material level sensing device bracket includes an elastic member connected between the first frame and the second frame, and the elastic member is configured to provide pulling force between the first frame and the second frame.

[0028] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0029] like Figures 1 to 4As shown, the material level sensing device bracket of the present invention includes a first frame 100 and a second frame 200, the first frame 100 and the second frame 200 are hingedly connected to each other, and the material level sensing device bracket is configured to be able to switch between an open state and a folded state; in the open state, the first frame 100 and the second frame 200 can respectively abut against the screen frame 600 of the concrete pumping machinery to prevent the material level sensing device bracket from falling from the screen frame 600, and in the folded state, the first frame 100 and the second frame 200 can respectively detach from the screen frame 600 to allow the material level sensing device bracket to detach from the screen frame 600; wherein, the first frame 100 and / or the second frame 200 are used to install the material level sensing device.

[0030] In the present invention, since the material level sensing device bracket is configured to be convertible between an open state and a folded state; in the open state, the first frame 100 and the second frame 200 can respectively abut against the screen frame 600 of the concrete pumping machinery to prevent the material level sensing device bracket from falling from the screen frame 600, and in the folded state, the first frame 100 and the second frame 200 can respectively detach from the screen frame 600 to allow the material level sensing device bracket to detach from the screen frame 600. Therefore, the material level sensing device bracket of the present invention can change the installation position according to the situation, and the disassembly and assembly are quick and convenient, and it is easy to replace after damage. Moreover, since the material level sensing device bracket is installed on the screen frame 600, the installation position is relatively high, and it is not easy to be submerged by concrete, and it is not easy to fall on it when concrete splashes.

[0031] It should be understood that the material level sensing device bracket can be designed in a variety of forms, as long as it can be converted between the above-mentioned open state and folded state. For example, the material level sensing device bracket includes a clamping claw, and the first frame 100 and the second frame 200 are respectively used as two claws of the clamping claw. When the material level sensing device bracket is in the open state, the first frame 100 and the second frame 200 can clamp the screen frame 600, thereby preventing the material level sensing device bracket from falling from the screen frame 600. When the material level sensing device bracket is in the folded state, the first frame 100 and the second frame 200 can be separated from the screen frame 600 respectively to allow the material level sensing device bracket to be separated from the screen frame 600. In one embodiment of the present invention, the material level sensing device bracket is designed as follows: in the open state, the angle between the first frame 100 and the second frame 200 is approximately 180°, and in the folded state, the angle between the first frame 100 and the second frame 200 is an obtuse angle.

[0032] In the above-mentioned embodiment, when the material level sensing device bracket is in an open state, it can be supported between the two beams of the screen frame 600 by the first frame 100 and the second frame 200. When disassembly is required, the first frame 100 and the second frame 200 are folded so that the angle between the first frame 100 and the second frame 200 is an obtuse angle. At this time, the overall length of the first frame 100 and the second frame 200 is reduced compared to the overall length in the open state, so that the material level sensing device bracket can be detached from between the two beams of the screen frame 600.

[0033] Further, in one embodiment of the present invention, the first frame 100 includes a first hook 110 capable of hooking the screen frame 600, the second frame 200 includes a second hook 210 capable of hooking the screen frame 600, and the material level sensing device bracket includes an elastic member 300 connected between the first frame 100 and the second frame 200, and the elastic member 300 is configured to provide a pulling force between the first frame 100 and the second frame 200. In this embodiment, the first hook 110 and the second hook 210 can be respectively hooked on two opposite beams of the screen frame 600, and the first frame 100 and the second frame 200 are mutually tightened by the elastic member 300 so that the first hook 110 and the second hook 210 are respectively hooked on the two beams.

[0034] Further, in one embodiment of the present invention, Figures 1 to 4 As shown, the material level sensing device bracket includes a leg 400 for being erected on the screen frame 600, and the leg 400 is arranged on the first frame 100, and the first frame 100 is used to install the material level sensing device. In this embodiment, when installing the material level sensing device bracket of the present invention, the leg 400 is first supported at a suitable position of the screen frame 600, and the first hook body 110 of the first frame 100 is used to hook the rib plate of the screen frame 600, and then the second hook body 210 is pressed down, and the second frame 200 rotates around the hinge point until the second hook body 210 hooks the rib plate of the screen frame 600, and then the second hook body 210 is released, and the elastic member 300 is tightened. At this time, the leg 400 applies a downward force to the screen frame 600, and the first hook body 110 and the second hook body 210 apply an upward force to the rib plate, so that the material level sensing device bracket is stably maintained in an open state. The disassembly process is opposite to the previous steps.

[0035] In order to make the first frame 100 more stably supported on the screen frame 600, in one embodiment of the present invention, the number of the legs 400 is two, and the two legs 400 are respectively arranged on both sides of the first frame 100. However, the number of the legs 400 can also be three, four, five, six, etc., as long as at least one leg 400 is arranged on both sides of the first frame 100.

[0036] Specifically, the first frame 100 and the second frame 200 are both L-shaped structures, and the first hook 110 and the second hook 210 are respectively arranged at the ends of the L-shaped structures. Such an arrangement can further improve the stability of the material level sensing device bracket.

[0037] Specifically, in one embodiment of the present invention, one end of the elastic member 300 is connected to the middle of the first frame 100 , and the other end of the elastic member 300 is connected to an end of the second frame 200 away from the second hook 210 .

[0038] The material level sensing device bracket of the present invention has the following advantages because it adopts the structure of the above-mentioned embodiment:

[0039] 1. The material level sensing device bracket of the present invention is not fixed by welding or bolts. The disassembly only requires rotating the second frame 200. The disassembly and assembly are quick and convenient. After installation, the bracket is reliably fixed. The installation position can be changed according to the situation. It is easy to replace after damage.

[0040] 2. The mounting position of the material level sensing device support of the present invention is relatively high, that is, it is located above the screen frame 600 of the hopper, so that it is not easily submerged by concrete, and concrete splashing is not easy to fall on it;

[0041] Therefore, the material level sensing device bracket of the present invention is easy to clean and is not easily bonded by concrete, causing the material level sensing device and its bracket to be scrapped; at the same time, it can also improve the false signal generated when the surface of the rod-type material level meter is completely wrapped by wet concrete, thereby improving the detection accuracy of the rod-type material level meter; in addition, when the material level sensing device bracket is relatively clean, it does not need to be disassembled and assembled for each operation, and can be moved with the screen frame 600.

[0042] The present invention also provides a material level sensing mechanism, which comprises a material level sensing device and the above-mentioned material level sensing device bracket.

[0043] Specifically, in one embodiment of the present invention, Figures 1 to 4 As shown, the material level sensing device includes a high material level meter 510 and a low material level meter 520 .

[0044] The method of using the material level sensing mechanism of the present invention is as follows: first, install the high material level meter 510 and the low material level meter 520 on the material level sensing device bracket; then, support the legs 400 of the material level sensing device bracket at a suitable position of the screen frame 600, and hook the ribs of the screen frame 600 with the first hook body 110 of the first frame body 100, and then press down the second hook body 210, and the second frame body 200 rotates around the hinge point until the second hook body 210 hooks the ribs of the screen frame 600, and then releases the second hook body 210, and the elastic member 300 is tightened. At this time, the legs 400 apply a downward force to the screen frame 600, and the first hook body 110 and the second hook body 210 apply an upward force to the ribs, so that the material level sensing device bracket is stably maintained in an open state. The disassembly process is opposite to the previous steps.

[0045] Furthermore, in one embodiment of the present invention, the material level sensing mechanism further comprises a protective cover for covering the material level sensing device and the material level sensing device bracket. The protective cover can prevent concrete from being poured or splashed onto the material level sensing device and the material level sensing device bracket from above or from the side.

[0046] The present invention further provides a concrete pumping machine, which includes a screen frame 600 and the above-mentioned material level sensing mechanism, and the material level sensing mechanism is installed on the screen frame 600 .

[0047] The preferred embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
