[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The specific embodiments of the present utility model are described in detail below.

[0026] like Figures 1 to 3 As shown, the utility model provides a specific embodiment of a loading and unloading device for laying cement cable troughs, comprising a base 1, wherein wheels 2 are respectively provided at the four corners of the bottom of the base 1;

[0027] One end of the base 1 is provided with an armrest 13, and the other end of the base 1 is open. Vertical plates 5 are fixedly supported in the middle of the two sides of the opening of the base 1. A horizontal plate 14 is fixedly supported across the tops of the two vertical plates 5. Side grooves 6 are provided on the inner sides of the vertical plates 5 in the upper and lower directions, and a loading and unloading device is provided in each side groove 6. An auxiliary pressing device is provided on the horizontal plate 14.

[0028] The loading and unloading device includes a connecting plate 11 that can move up and down along the side groove 6, and the end of the connecting plate 11 extending out of the side groove 6 is provided with a supporting plate 12 that supports and cooperates with the end of the cement cable trough;

[0029] The auxiliary pressing device includes a telescopic rod 15 arranged at the lower part of the horizontal plate 14. The end of the telescopic rod 15 is provided with a pressing plate 7, and the pressing plate 7 can be pressed and matched with the middle part of the cement cable trough.

[0030] When in use, the loading and unloading device is first used to make the support plate 12 fit on the ground, and the handrail 3 is used to control the walking direction of the wheel 2. The base 1 is wrapped and inserted from both sides of the cement cable trough, and the support plate 12 is inserted into the bottom end surface of the cement cable trough. The support plate 12 will lift the cement cable trough off the ground, and then by activating the telescopic rod 15, the pressing plate 7 will press on the upper end surface of the cement cable trough, so that the cement cable trough can be transported, saving manpower and being safer and more efficient. Specifically, the pressing plate 7 in this embodiment is made of rubber material, which can avoid the pressure loss caused by rigid compression on the cement cable trough.

[0031] When it reaches the installation site, with the help of the lifting and lowering of the connecting plate 11, the supporting plate 12 will drive the cement cable trough to descend to the laying depth. With the help of the movement of the wheels 2, the supporting plate 12 can be pulled out from the bottom of the cement cable trough, thus completing the unloading of the cement cable trough, which is very convenient and greatly improves the laying efficiency of the cement cable trough, and is worthy of promotion.

[0032] In this embodiment, the telescopic rod 15 can be an electric push rod, an air cylinder, an oil cylinder or other specific equipment to achieve the up and down displacement of the pressing plate 7.

[0033] like Figure 2 As shown, this embodiment provides a specific implementation of a loading and unloading device, that is, the loading and unloading device also includes a screw rod 10 rotatably arranged in the side groove 6, the screw rod 10 is arranged in the up-down direction, the connecting plate 11 is penetrated by the screw rod 10 and threadedly engaged with the screw rod 10, and two guide rods 13 are arranged in the up-down direction in the side groove 6, and the guide rods 13 movably penetrate the connecting plate 11. In this embodiment, the lifting and lowering of the support plate 12 is achieved through the rotation of the screw rod 10 and the guiding effect of the guide rods 13, so that the cement cable trough on the ground can be scooped up and transported. When unloading, the cement cable trough can be unloaded to a deeper place, realizing the purpose of automatic loading and unloading, greatly saving manpower input and improving construction progress.

[0034] In practice, the screw rod 10 can be rotated manually or electrically. When electrically rotating, a motor 9 is mounted at the top of the vertical plate 5, with the output end of the motor 9 coaxially connected to the end of the screw rod 10. Specifically, the motor 9 is a motor with a speed reducer. By starting the motor 9, the screw rod 10 rotates and drives the connecting plate 11 to slide up and down within the side groove 6.

[0035] Furthermore, in order to improve the telescopic operation stability of the telescopic rod 15, two guide rods 2 4 are provided on the upper surface of the pressure plate 7. The lower ends of the guide rods 2 4 are fixedly connected to the pressure plate 7, and the upper ends of the guide rods 2 4 are movable through the horizontal plate 14.

[0036] Furthermore, an end plate 8 is provided at the end of the guide rod 24 located on the upper part of the transverse plate 14 and is engaged with the transverse plate 14 in a stop position.

[0037] like Figure 2 As shown, the connecting plate 11 is L-shaped, and the horizontal section of the connecting plate 11 is located in the side groove 6, and the vertical section of the connecting plate 11 is connected to the supporting plate 12. Since the cement cable trough has a certain depth when it is laid, the connecting plate 11 is L-shaped to facilitate the lowering of the supporting plate 12 to a certain depth.

[0038] The above description is only a specific embodiment of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions have been made with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and such modifications or replacements do not deviate from the essence of the corresponding technical solutions within the scope of the technical solutions of the embodiments, and they should all be covered by the scope of protection of the claims.
