[0022] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example 1 Reference Figures 1-2 This is the first embodiment of the present invention. This embodiment provides a trestle slipform paver, including a frame assembly 100 and a main body assembly 200. By installing the main body assembly 200 on the frame assembly, the vibration and paving devices are integrated, realizing the simultaneous vibration operation during paving, and solving the problem that it is difficult to ensure the vibration coverage and flatness of the surface during existing manual operations.

[0025] Specifically, the frame component 100 includes a fixed frame 101 and a paving box 102. The fixed frame 101 is disposed on the upper part of the paving box 102 and is fixedly connected to the paving box 102. The movement and height of the paving box 102 are controlled by the movement of the fixed frame 101. Furthermore, the main component 200 includes a guide 201, a transmission component 202, a vibrating component 203, a smoothing component 204, an adjusting component 205, and a power component 206. The transmission component 202 is located on one side of the fixed frame 101 and is connected to the fixed frame 101. The position and height of the fixed frame 101 are adjusted through the transmission component 202, thereby further controlling the paving box. Specifically, the transmission component 202 includes a transmission column 202a, a transmission connecting rod 202b, and a transmission box 202c. The transmission column 202a is connected to one side of the fixed frame 101. The fixed frame 101 is driven to change position and height by following the transmission column 202a. The transmission box 202c is connected to the transmission column 202a through the transmission connecting rod 202b. The transmission connecting rod 202b is movably connected to the connecting protrusion 202a-1 on the transmission column 202a and the connecting side ear 202c-1 on the transmission box 202c, so that the transmission box 202c can remain stable when the transmission column 202a moves up and down. Furthermore, the power component 206 includes a reducer 206a and a power motor 206b. The reducer 206a is located inside the transmission box 202c, and the power motor 206b is located on one side of the transmission box 202c and connected to the reducer 206a. Preferably, the power motor 206b can be a variable frequency motor. The reducer 206a and the power motor 206b are combined to form a drive unit. A set of drive units is configured on each side of the overall device, so that the device has a power source.

[0026] Furthermore, the guide member 201 is located on one side of the transmission member 202, and guide members 201 are provided on both sides and connected to the transmission member 202. The guide member 201 is used to ensure a more stable direction of travel when the driven member 206 moves through the transmission member 202. The vibrating member 203 is connected to the fixed frame 101, and the smoothing member 204 is connected to the side wall of the paving box 102, so that the whole device can perform both vibration and smoothing functions when moving forward. The adjusting member 205 is located on one side of the fixed frame 101, and a set of adjusting members 205 is provided at each of the four corners of the device. The adjusting members 205 connect the fixed frame 101 and the paving box 102, and the horizontal position and vertical relationship between the paving box 102 and the fixed frame 101 are realized through the adjusting members 205.

[0027] In use, the device is first connected to the outer frame of the trestle via the guide component 201, that is, the entire device is connected to the trestle frame. When the power component 206 is started, the power component 206 drives the transmission component 202, which in turn drives the fixed frame 101, and then drives the paving box 102 to move. When the work begins, the vibrator 203 and the smoothing component 204 start working, and vibrate and smooth simultaneously. When it is necessary to adjust the height distance between the smoothing component 204 and the smoothing surface, or to adjust the left and right position relationship, it is achieved through the adjusting component 205.

[0028] In summary, integrating vibration and smoothing into a single device solves the problems of incomplete vibration coverage and inability to guarantee the flatness of the smoothing surface that occur during manual operations.

[0029] Example 2 Reference Figures 1-4 This is the second embodiment of the present invention, which provides supplementary explanation of the first embodiment.

[0030] Specifically, the power component 206 also includes a power gear 206c and a power shaft 206d. One end of the power shaft 206d passes through the side wall of the transmission box 202c and is connected to the reducer 206a. The power gear 206c is located at the other end of the power shaft 206d and is connected to the power shaft 206d.

[0031] Furthermore, the guide component 201 includes a vertical guide wheel 201a, a vertical guide wheel 201b, a guide rack 201c, a stabilizing pressure wheel 201d, and a guide base 201e. The guide base 201e is fixedly connected to the side wall of the transmission column 202a. The vertical guide wheel 201a and the vertical guide wheel 201b are set on the side wall of the guide base 201e. There are two vertical guide wheels 201a, which are connected to the bottom of the outer frame of the trestle in the middle. There is one vertical guide wheel 201b, which is in contact with the bottom of the outer frame of the trestle. This enables the overall device to be reliably fixed and relatively slidable on the trestle host. Moreover, the vertical guide wheel 201a and the vertical guide wheel 201b are roller structures, which can effectively reduce the running resistance of the equipment and extend the service life of the equipment. The stabilizing pressure roller 201d is located on the side wall of the transmission box 202c and corresponds vertically to the power gear 206c. The guide rack 201c is located between the power gear 206c and the stabilizing pressure roller 201d, and the toothed side of the guide rack 201c meshes with the power gear 206c. The surface of the guide rack 201c is provided with bolt holes 201c-1. The guide rack 201c is connected to the two side frames of the trestle through the bolt holes 201c-1, fixing the guide rack 201c to the outer frame of the trestle. Through the rotation of the power gear 206c, the meshing between the teeth drives the operation of the entire device. Through the gear and rack structure on both sides, constant speed drive is achieved, and the speed control problem is solved. Preferably, the function of the stabilizing pressure roller 201d is to apply force to the connection between the guide rack 201c and the power gear 206c, which can make the connection between the two tighter and prevent misalignment during the forward movement, thus affecting the construction progress.

[0032] Furthermore, the adjusting component 205 includes a horizontal slide block 205a and a vertical slide block 205b. The horizontal slide block 205a is disposed on one side of the paving box 102, and the vertical slide block 205b is disposed on one side of the fixed frame 101. The adjusting component 205 also includes a horizontal slider 205c and a vertical slider 205d. The horizontal slider 205c is movably connected to a horizontal slide rod 205a-1 disposed on the horizontal slide block 205a, and the vertical slider 205d is connected to a vertical slide rod 205a-1 disposed on the vertical slide block 205b. The vertical slide bar 205b-1 is movably connected, and one end of the vertical slide bar 205b-1 is connected to one side of the horizontal slider 205c. The horizontal slider 205c moves left and right on the horizontal slide bar 205a-1, causing the paving box 102 to move left and right. The vertical slider 205d moves up and down on the vertical slide bar 205b-1, causing the paving box 102 to adjust its vertical position. Thus, during construction, the height and left and right position of the lower paving box 102 can be adjusted.

[0033] Furthermore, the smoothing component 204 includes a cement forming mold 204a and a trowel 204b. The cement forming mold 204a is fixedly connected to the side wall of the paving box 102. According to the design of the cement forming surface and the graphic dimensions of the forming surface, the trowel 204b is connected to the cement forming mold 204a through a trowel connecting frame 204b-1, and a counterweight block 204b-2 is provided above the trowel 204b. The vibrating component 203 includes a vibrating rod assembly 203a and a floating plate vibrator 203b. The vibrating rod assembly 203a is connected to the inner wall of the fixed frame 101 through a mounting crossbar 203a-1, and the floating plate vibrator 203b is set on one side of the cement forming mold 204a. Preferably, the vibrator assembly 203a adopts a built-in motor structure, and the vibration frequency is adjustable from 5000 to 12000 times / minute. It has high vibration efficiency, reduces the phenomenon of missed vibration and missing vibration that exists in manual vibration, and improves the internal structural quality and surface aesthetics of concrete.

[0034] Preferably, the main component 200 also includes a hydraulic power pump station 207 and an electrical control box 208. The hydraulic power pump station 207 and the electrical control box 208 are installed on the side wall of the fixed frame 101. The hydraulic power pump station 207 drives the hydraulic cylinder to control the height of the paving box, that is, the control adjustment component 205. The height of the cylinder is controlled by a solenoid valve with a high corresponding frequency. The electrical control box 208 houses electrical control components and an onboard controller, which work together to control the operation of the entire machine.

[0035] In summary, the device of the present invention can be reliably fixed at the bottom of the trestle, and the transmission adopts a gear and rack mechanism to realize the constant speed and positioning movement of the paving equipment. It has a cement casting mold and a built-in vibrator, and can realize automatic paving, automatic vibration and automatic smoothing.

[0036] Example 3 Reference Figures 1-2 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but it differs from the other embodiments in that it provides a method for using a trestle slipform paver.

[0037] Specifically, first fix the guide rack 201c to the side wall of the trestle frame. The guide rack 201c is generally 35m long. Then assemble the whole device in sequence and connect it to the bottom of the trestle. When the machine starts working, control the whole machine through the electrical control box 208 and control the height of the paving box 102 through the hydraulic power pump station 207, and simultaneously vibrate and smooth the concrete.

[0038] In summary, by using this device, the problem of difficulty in controlling the vibration coverage and flatness of existing manual operations is solved, thus improving construction efficiency and reducing costs.
