[0033] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Please see Figures 1-6 The present invention will describe the above technical solution in detail through the following embodiments:

[0035] The height adjustment structure for tunnel lining formwork trolleys is based on existing tunnel lining formwork trolley structures, such as... Figure 1 and Figure 2 As shown, the device in this embodiment includes a U-shaped fixing frame 2 fixedly installed at the position of the crossbeam 101 on the trolley 1, and a first screw 3 is installed on the U-shaped fixing frame 2 by means of a motor rotation.

[0036] like Figure 3 and Figure 4 The structure shown has a movable component 4 installed on the first screw 3. Specifically, in this embodiment, the movable component 4 includes a vertical frame 42 with a top frame 43 and a bottom frame 41 fixedly installed at the upper and lower ends. In this embodiment, a protrusion 46 is installed at the upper end of the vertical frame 42, and a first threaded hole 461 is provided on the protrusion 46. Based on the screw principle, this part of the movable component 4 can move horizontally along the first screw 3, which makes it convenient for workers to observe the pouring situation of various parts of the trolley over a wide range.

[0037] To facilitate workers' access and reduce the inconvenience of climbing traditional fixed scaffolds, a second screw 44 is installed between the top frame 43 and the bottom frame 41 via a drive motor 45. A transmission frame 52 is threaded onto the second screw 44, and a pallet body 51 is horizontally installed on the transmission frame 52. A work basket 6 is installed on the pallet body 51.

[0038] This implementation example Figures 4-6 The structure shown has an inner groove 421 on the vertical frame 42. In order to reduce the frictional force of lifting and lowering, rollers 53 for lifting and lowering along the inner groove 421 are rotatably installed on both sides of the transmission frame 52. The rollers 53 are attached to the inner wall of the inner groove 421. In order to obtain the lifting and lowering force, a second threaded hole 5201 for threaded installation of the second screw 44 is provided on the transmission frame 52.

[0039] However, considering the relatively high lifting height, relying solely on the second screw 44 to support gravity is unreliable. Therefore, a middle partition plate 521 is provided on the transmission frame 52, and the middle partition plate 521 is equipped with... Figure 6 The open slot 5211 shown.

[0040] In this embodiment, a pressure block 55 is installed on the middle partition plate 521 and located at the open groove 5211. The pressure block 55 has inclined structures at both ends, and clamping blocks 54 are provided on both sides of the pressure block 55. The clamping blocks 54 adopt a trapezoidal structure corresponding to the inclined surfaces, which can make the clamping blocks 54 squeeze out along the side hole 5202 and adhere to the groove wall of the inner groove 421 when the pressure block 55 is pressed.

[0041] To improve the clamping effect, this embodiment, for example Figure 6 In terms of position, a convex plate 541 is provided at the bottom of the clamping block 54, and a spring is installed between the two convex plates 541. The spring provides the ability to center and reset. A hydraulic cylinder 56 is installed between the pressure block 55 and the transmission frame 52. The hydraulic cylinder 56 drives the pressure block 55 to rise and fall vertically to obtain a clamping force, thereby improving stability.

[0042] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0043] Furthermore, if the embodiments of this utility model involve descriptions such as "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
