Description

Technical Field

[0001] This utility model relates to the field of grouting machine technology for anchor bolt trolleys, and in particular to a grouting machine lifting mechanism for anchor bolt trolleys. Background Technology

[0002] During tunnel construction and anchor bolt support operations, grouting is often required for tunnel sections with unstable surrounding rock to reinforce the rock, reduce deformation, and prevent collapse. The main equipment used for anchor bolt support is the anchor bolt trolley, while grouting operations typically require a separate grouting machine.

[0003] In existing technologies, most anchor bolt trolleys do not integrate grouting machines, requiring separate transportation and installation of grouting equipment, resulting in long relocation times, low on-site operation efficiency, and difficulties in coordinating operations in confined spaces.

[0004] Some technical solutions involve fixing the grouting machine to a high-level structure on the anchor trolley body. While this saves space for equipment layout, it requires operators to lift the materials to a higher position when adding cement and auxiliary materials, resulting in high labor intensity and affecting both work efficiency and safety.

[0005] Therefore, how to design a grouting machine installation structure that can be easily raised and lowered on the anchor bolt trolley to reduce the material loading height, improve work efficiency and ensure operational safety is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] The purpose of this utility model is to provide a grouting machine lifting mechanism for anchor bolt trolleys, so as to realize the smooth lifting of the grouting machine assembly, thereby effectively reducing the material loading height, reducing the labor intensity of operators, and improving the efficiency and safety of grouting operations.

[0007] This utility model is achieved using the following technical solution: a grouting machine lifting mechanism for an anchor bolt trolley, characterized in that it includes a grouting machine assembly, a grouting machine mounting bracket, a lifting cylinder, a cylinder fixing bracket, a cylinder lifting bracket, a left pulley assembly, and a right pulley assembly. The cylinder fixing bracket, left pulley assembly, and right pulley assembly are respectively fixedly installed at corresponding positions on the anchor bolt trolley. One end of the lifting cylinder is hinged to the cylinder fixing bracket via a pin, and the other end is hinged to the cylinder lifting bracket via a pin. The cylinder lifting bracket is fixedly connected to the grouting machine mounting bracket. The grouting machine assembly is fixed on the grouting machine mounting bracket. The rear end of the grouting machine mounting bracket is provided with a sliding groove. The left pulley assembly and right pulley assembly are respectively disposed within the sliding groove to limit the forward and backward and left and right displacements of the grouting machine mounting bracket, thereby driving the grouting machine assembly to lift as a whole under the drive of the lifting cylinder.

[0008] Furthermore, the left pulley assembly and the right pulley assembly are symmetrical structures, both of which include a welded bracket, a lifting auxiliary pulley, and a lifting main pulley. The lifting auxiliary pulley and the lifting main pulley are fixed to the welded bracket by pins.

[0009] Furthermore, the right pulley assembly and the left pulley assembly are arranged in a mirror image of each other in structure.

[0010] Furthermore, the groove is a recessed groove set along the length direction of the grouting machine mounting bracket, and the two side walls are used to roll with the wheel rims of the lifting auxiliary pulley and the lifting main pulley.

[0011] Furthermore, both the cylinder fixing bracket and the cylinder lifting bracket are connected to the anchor trolley frame by bolts.

[0012] Furthermore, the lifting cylinder is a hydraulic telescopic cylinder.

[0013] Furthermore, when the grouting machine assembly is lowered to its lowest position, the height of its feed port is lower than the operator's shoulder height.

[0014] The grouting machine lifting mechanism for anchor bolt trolley described in this utility model has the following advantages: The grouting machine assembly is smoothly raised and lowered by a pulley system and hydraulic cylinder drive, reducing lateral sway and improving stability and safety during the lifting process. The lowered loading port height allows operators to add cement and auxiliary materials from a comfortable position, significantly reducing labor intensity. The integrated design of the grouting machine lifting mechanism and the anchor bolt trolley structure reduces the time required for transporting and installing additional equipment, improving on-site construction efficiency. The simple structure, easy installation, and strong adaptability allow for adjustments based on different anchor bolt trolley models. The lifting mechanism can raise the grouting machine to a high position without obstructing the normal passage of the trolley, balancing the space requirements for operation and equipment access.

Example

[0019] like Figure 1 As shown, a grouting machine lifting mechanism for an anchor bolt trolley includes a lifting cylinder 1, a grouting machine assembly 2, a grouting machine mounting bracket 3, a cylinder fixing bracket 4, a cylinder lifting bracket 5, a left pulley assembly 6, and a right pulley assembly 7. The left pulley assembly 6 and the right pulley assembly 7 are symmetrical structures, and both include a welded bracket 61, a lifting auxiliary pulley 62, and a lifting main pulley 63.

[0020] Specifically, the cylinder fixing bracket 4, the left pulley assembly 6, and the right pulley assembly 7 are fixed to their respective positions on the anchor trolley using bolts, and their positions remain fixed after installation. One end of the lifting cylinder 1 is hinged to the cylinder fixing bracket 4 via a pin, and the other end is hinged to the cylinder lifting bracket 5 via a pin. The cylinder lifting bracket 5 is then connected to the grouting machine mounting bracket 3 via bolts. The grouting machine assembly 2 is fixed above the grouting machine mounting bracket 3, and the rear end of the grouting machine mounting bracket 3 is provided with a sliding groove extending in the front-to-back direction.

[0021] The lifting auxiliary pulley 62 and lifting main pulley 63 of the left pulley assembly 6 and the right pulley assembly 7 are respectively embedded in the slide groove of the grouting machine mounting bracket 3, and cooperate with the slide groove to restrict their displacement in the front-back and left-right directions; the lifting auxiliary pulley 62 and lifting main pulley 63 are fixed on the welding bracket 61 by a pin to form the left pulley assembly 6, and the right pulley assembly 7 is arranged in a mirror image of the left pulley assembly 6 in structure.

[0022] When the grouting machine is in operation, the operator operates the lifting switch through the control panel to extend and retract the lifting cylinder 1. When the lifting cylinder 1 extends, it drives the cylinder lifting bracket 5 and the grouting machine mounting bracket 3 connected to it to move upward as a whole, raising the grouting machine assembly 2 to facilitate operation or equipment passage; when the lifting cylinder 1 retracts, the grouting machine assembly 2 lowers as a whole, reducing the material loading height, making it easier for the operator to add cement and auxiliary materials, and reducing labor intensity.

[0023] In this embodiment, the pulley guide structure works in conjunction with the hydraulic cylinder drive to ensure that the grouting machine is stable and reliable during lifting and lowering, without lateral swaying, thus improving operational safety and stability.
