DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1

[0025] like Figure 1-5 As shown, in this embodiment, a lifting mechanism of an anchor trolley grouting machine is mainly disclosed, which can be installed on the outside of an existing anchor trolley 1, including a grouting machine 2, a fixed seat 3 and a mounting seat 4. The fixed seat 3 is connected to the anchor trolley 1 by bolts, and the mounting seat 4 is slidably connected to the fixed seat 3. The grouting machine 2 is bolted to the mounting seat 4, and a horizontal axis 31 is vertically slidably connected to the fixed seat 3. A driving cylinder 32 is also provided on the fixed seat 3, and the cylinder end of the driving cylinder 32 is fixed to the fixed seat 3. The end of the piston rod of the driving cylinder 32 is vertically connected to the horizontal axis 31. The fixed seat 3 and the mounting seat 4 are connected. A chain 5 is provided, one end of which is fixed to the bottom of the fixed seat 3, and the other end is fixed to the mounting seat 4 after passing through the horizontal axis 31, forming a movable pulley structure. The driving cylinder 32 is extended and retracted to drive the horizontal axis 31 to rise and fall. The mounting seat 4 is lifted and lowered through the transmission of the chain 5. The distance that the mounting seat 4 slides up and down is twice the stroke of the driving cylinder 32. In the initial state, the mounting seat 4 is overlapped and stored with the fixed seat 3, which is convenient for the passage of the trolley. When grouting is required, the mounting seat 4 drives the grouting to descend, and returns to the initial state after use, thereby improving construction efficiency and safety and reducing the labor intensity of operators.

[0026] Furthermore, in the specific implementation, Figure 2-5As shown, the above-mentioned fixing seat 3 provided in the embodiment of the utility model is respectively provided with first slide grooves 33 on both sides inwardly, and the first pulley 41 that slides and cooperates with the first slide groove 33 is provided on the upper part of the mounting seat 4, and the second slide grooves 42 are respectively provided on both sides of the mounting seat 4. The first slide groove 33 and the second slide groove 42 can be fixed by welding with channel steel, and the second pulley 34 that slides and cooperates with the second slide groove 42 is respectively provided on both sides of the lower part of the fixing seat 3. Specifically, L-shaped ears 38 are provided on both sides of the lower part of the fixing seat 3, and the second pulley 34 is pin-connected to the ears 38. The pulley 34 faces the inside of the support ear 38, and the two ends of the transverse axis 31 are respectively provided with a third pulley 35 that slides with the first slide groove 33. The third pulley 35 is arranged above the first pulley 41. In the initial state, the first pulley 41 is located above the first slide groove 33, and the second pulley 34 is located below the second slide groove 42. The driving cylinder 32 is in an extended state. When grouting is required, the driving cylinder 32 retracts, the mounting seat 4 descends, and the position of the second pulley 34 is relatively fixed. The first pulley 41 slides down along the first slide groove 33 toward the second pulley 34, thereby realizing a limited sliding connection between the mounting seat 4 and the fixed seat 3.

[0027] Furthermore, in the specific implementation, Figure 2 , 3 As shown, a sprocket 36 for limiting the chain 5 is sleeved on the above-mentioned horizontal axis 31 provided in the embodiment of the utility model, and the connection points of the sprocket 36 and both ends of the chain 5 are located in the same vertical plane, so that the chain 5 is limited in the sprocket 36 and is driven according to the guide of the sprocket 36, thereby improving the stability and efficiency of the transmission.

[0028] Furthermore, in the specific implementation, Figure 3 , 4 As shown, a first positioning hole 37 is provided on the above-mentioned fixing seat 3 provided in the embodiment of the utility model, and a second positioning hole 44 aligned with the first positioning hole 37 is provided on the mounting seat 4. The first positioning hole 37 and the second positioning hole 44 are detachably connected with a positioning pin 6, which plays a positioning role when the lifting mechanism is assembled, and plays a fixing role when the anchor trolley 1 is moved and transported, so as to facilitate folding and storage.

[0029] Embodiment 2

[0030] like Figure 6 , 7As shown, in this embodiment, the main structure is exactly the same as that of the first embodiment, and the difference lies in that the lifting mechanism can be installed inside the existing anchor trolley 1, and the fixed seat 3 includes vertical rods 30 on both sides, and pulley groups 43 for limiting the vertical movement of the vertical rods 30 are provided on both sides of the mounting seat 4. The same thing is that the cooperation between the first pulley 41 and the first slide groove 33 is different from the cooperation between the second pulley 34 and the second slide groove 42 in the first embodiment. In this embodiment, the pulley group 43 cooperates with the vertical rods 30 on both sides of the mounting seat 4, and the vertical rod 30 is limited and abutted between the pulley groups 43, so as to realize the vertical limited sliding connection between the fixed seat 3 and the mounting seat 4.

[0031] Furthermore, in the specific implementation, Figure 6 As shown, a balancing valve 7 for abutting and locking the position of the mounting seat 4 is provided on the above-mentioned fixed seat 3 provided in the embodiment of the utility model. The balancing valve 7 is started to abut the mounting seat 4 to adjust the descending position and lock it to prevent further falling. At the same time, the balancing valve 7 has a certain damping effect on the mounting seat 4, which can stabilize it to a certain extent during the rising and falling process.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
