[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example 1:

[0025] Please see Figure 1-4 This utility model provides a technical solution: a sliding base for a tunnel construction trolley, comprising: a support base 1, fixed bases 2 on both the front and rear sides of the support base 1, mounting plates 3 on both sides of the upper end of the fixed base 2, mounting locking parts 4 fixedly connected around the upper end of the mounting plates 3, an adjustment component 5 and an adjustment component 6, the adjustment component 5 being located on the fixed base 2 and used to adjust the installation spacing of the mounting plates 3, and the adjustment component 6 being located in the fixed base 2 and used to adjust the installation position of the support base 1.

[0026] In this embodiment, when it is necessary to adjust the fixed position of the mounting plate 3, the bidirectional hydraulic rod 61 drives the moving plate 62 to move outward. The moving plate 62 drives the support beam 63 to move outward through the guide block 7 and the guide rod 8, so that the support beam 63 pushes the fixed seat 2 outward, and the fixed seat 2 drives the mounting plate 3 outward.

[0027] Example 2:

[0028] Please see Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: the adjustment component 5 includes a stepper motor 51, the output end of which passes through the fixed base 2 and is fixedly connected to a positive and negative lead screw 52. Nut seats 53 are threaded onto both sides of the surface of the positive and negative lead screw 52. A fixing post 54 is fixedly connected to the upper end of the nut seat 53. The upper end of the fixing post 54 extends above the fixed base 2 and is fixedly connected to the lower end of the mounting plate 3. The adjustment component 6 includes a bidirectional hydraulic rod 61, the output end of which is fixedly connected to a moving plate 62. The moving plate 62 has two ends on one side... Each support beam 63 is fixedly connected to the support base 1. One end of the support beam 63 extends through to the outside of the support base 1 and is fixedly connected to one side of the fixed base 2. Guide blocks 7 are fixedly connected to both sides of the support beam 63. Guide rods 8 are slidably connected inside the guide blocks 7. The guide rods 8 are longitudinally fixedly connected in the support base 1. One end of the positive and negative screw rods 52 is sleeved with a bearing seat, and one side of the bearing seat is fixedly connected to one side inside the fixed base 2. Slide grooves 9 are opened on the front and rear sides of the upper end of the fixed base 2. Slide blocks 10 are slidably connected inside the slide grooves 9.

[0029] In this embodiment: the stepper motor 51 drives the positive and negative lead screws 52 to start rotating through the bearing seat. The positive and negative lead screws 52 drive the nut seat 53 to move relative to each other. The nut seat 53 drives the fixed column 54 to move relative to each other. The fixed column 54 drives the mounting plate 3 to start moving through the slide groove 9 and the slider 10, so that the fixed spacing of the mounting plate 3 is moved to the designated position, which facilitates the installation of the tunnel construction trolley.

[0030] The working principle of the sliding base of the tunnel construction trolley provided by this utility model is as follows:

[0031] Implementation steps for the first innovation point:

[0032] Step 1: When it is necessary to adjust the fixed position of the mounting plate 3, the bidirectional hydraulic rod 61 drives the moving plate 62 to move outward, and the moving plate 62 drives the support beam 63 to move outward through the guide block 7 and the guide rod 8.

[0033] Step 2: Push the support beam 63 outward to the fixed seat 2, and the fixed seat 2 will drive the mounting plate 3 outward.

[0034] Implementation steps for the second innovation point:

[0035] Step 1: Simultaneously, stepper motor 51 drives forward and reverse lead screw 52 to start rotating through bearing seat. Forward and reverse lead screw 52 drives nut seat 53 to move relative to each other. Nut seat 53 drives fixed column 54 to move relative to each other.

[0036] Step 2: The fixed column 54 drives the mounting plate 3 to move through the sliding groove 9 and the slider 10, so that the fixed spacing of the mounting plate 3 is moved to the designated position, which facilitates the installation of the tunnel construction trolley.
