Description
Technical Field
[0001] The utility model relates to the field of grouting devices, and particularly to an underground grouting pump trolley. Background Art
[0002] Underground goafs are mines underground. During the mining process, after the primary ore bodies are cut and mined out, large and small spaces with basically no ore bodies are formed. Most goafs need to release pressure through caving and filling. Some goafs will cause ground subsidence and damage farmland. In order to avoid the collapse of goafs, grouting is carried out on the goafs.
[0003] Since the grouting device needs to grout goafs at different positions, it needs to be moved. In order to facilitate the movement of the grouting device, a pull rod is installed at the front end of the grouting device. Although the pull rod is movably installed on the grouting device, when moving the grouting device, the pull rod cannot be hidden and placed. Coupled with the fact that the pull rod has a certain length, when underground, the pull rod will affect the work of the staff. Summary of the Utility Model
[0004] The main purpose of the utility model is to provide an underground grouting pump trolley, which can effectively solve the problems in the background art.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] An underground grouting pump trolley, characterized in that: it includes a base, a pump box and a pull rod. The upper surface of the base is fixedly installed with a pump box. The lower surface of the base and near the four corners are movably installed with rollers. The front end surface of the base and below is fixedly installed with an extension plate. The upper surface of the extension plate is movably embedded with a limit slider. The upper surface of the limit slider is movably installed with a positioning member. A pull rod is movably installed in front of the positioning member. The front end surface of the base and above the extension plate is provided with a storage groove. The lower surface of the inner part of the storage groove and the upper surface of the extension plate are both provided with limit chutes; the limit chute on the lower surface of the inner part of the storage groove is communicated with the limit chute on the upper surface of the extension plate, and the limit slider is embedded in the limit chute.
[0007] Preferably: The positioning member includes a sleeve, a positioning column, a stop block, a spring, a rotating block and a support block. The inside of the sleeve is movably embedded with a positioning column. The lower surface of the positioning column is fixedly installed with a stop block. A spring is provided below the stop block inside the sleeve. The lower surface of the sleeve is fixedly installed with a rotating block. Support blocks are fixedly installed on both side surfaces of the sleeve. The front end surface of the base and above is fixedly installed with a positioning sleeve block. The upper end of the positioning column is embedded in the positioning sleeve block.
[0008] Preferably, a rotation groove is formed on the upper surface of the limit slider, the rotation block is movably embedded in the rotation groove, and the positioning member is movably connected to the limit slider through the rotation block.
[0009] Preferably, the pull rod is movably installed between the support blocks on both sides of the sleeve.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] In the utility model, by arranging the base, the limit slider, the positioning member and the pull rod to cooperate with each other, when the grouting device is pulled to the designated area through the pull rod, the pull rod is turned downward so that the pull rod is turned into a horizontal state, and then the positioning column of the positioning member is pushed out of the positioning sleeve block of the base by using a tool, and then the pull rod is pushed so that the positioning member moves into the storage groove of the base until the pull rod is pushed into the storage groove of the base to the maximum extent, so that the pull rod can be hidden and placed.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] In order to make the technical means, creative features, achieving purposes and effects of the utility model easy to understand, the utility model is further elaborated below in conjunction with specific embodiments.
[0018] As Figures 1-4As shown in the figure, a downhole grouting pump trolley includes a base 1, a pump box 2, and a pull rod 5. The pump box 2 is fixedly installed on the upper surface of the base 1. Rollers 6 are movably installed on the lower surface of the base 1 near the four corners. An extension plate 101 is fixedly installed on the front end surface of the base 1 and below. A limit slider 3 is movably embedded on the upper surface of the extension plate 101. A positioning member 4 is movably installed on the upper surface of the limit slider 3. A pull rod 5 is movably installed in front of the positioning member 4.
[0019] A storage groove 103 is formed on the front end surface of the base 1 and above the extension plate 101. Limit sliding grooves 104 are formed on the lower surface of the interior of the storage groove 103 and the upper surface of the extension plate 101. A positioning sleeve block 102 is fixedly installed on the front end surface of the base 1 and above. The limit sliding groove 104 has a limiting effect on the limit slider 3, which can prevent the limit slider 3 from separating from the base 1. A rotating groove 301 is formed on the upper surface of the limit slider 3. The limit sliding groove 104 on the lower surface of the interior of the storage groove 103 communicates with the limit sliding groove 104 on the upper surface of the extension plate 101. The limit slider 3 is embedded in the limit sliding groove 104, and there is a certain frictional force between the limit slider 3 and the limit sliding groove 104. The positioning member 4 includes a sleeve 401, a positioning column 402, a stop block 403, a spring 404, a rotating block 405, and a support block 406. The spring 404 has an external force that pushes the stop block 403 upward. The positioning column 402 is movably embedded in the interior of the sleeve 401. The stop block 403 is fixedly installed on the lower surface of the positioning column 402. The spring 404 is provided below the stop block 403 inside the sleeve 401. The rotating block 405 is fixedly installed on the lower surface of the sleeve 401. Support blocks 406 are fixedly installed on both side surfaces of the sleeve 401. The support blocks 406 can assist the flexible flipping of the pull rod 5. The rotating block 405 is movably embedded in the rotating groove 301. The positioning member 4 is movably connected to the limit slider 3 through the rotating block 405. The cooperation between the rotating block 405 and the rotating groove 301 can assist the rotation of the positioning member 4. The upper end of the positioning column 402 is embedded in the positioning sleeve block 102. The pull rod 5 is movably installed between the support blocks 406 on both sides of the sleeve 401.
[0020] It should be noted that the present utility model is an underground grouting pump trolley. When in use, after the grouting device is pulled to the designated area through the pull rod 5, the pull rod 5 is flipped downward so that the pull rod 5 is flipped to a horizontal state. Then, a tool is used to push the positioning column 402 of the positioning member 4 out of the positioning sleeve block 102 of the base 1, and then the pull rod 5 is pushed so that the positioning member 4 moves into the receiving groove 103 of the base 1 until the pull rod 5 is pushed into the receiving groove 103 of the base 1 to the maximum extent, so that the pull rod 5 can be hidden and placed. When the pull rod 5 is used again, the pull rod 5 is pulled out of the receiving groove 103. During the pulling process of the pull rod 5, the limit slider 3 and the positioning member 4 are driven to move. When the positioning member 4 moves to the maximum extent, the upper end of the positioning column 402 of the positioning member 4 will be embedded in the positioning sleeve block 102 under the pushing action of the spring 404, so that the positioning member 4 and the limit slider 3 can be limited. At this time, the pull rod 5 can be rotated up and down and left and right.
[0021] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
