[0030] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0031] 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; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0033] Reference Figures 1 to 5 This embodiment provides a concrete precast trough transport trolley, including a loading platform 1, a track wheel assembly 2, a support frame 3 and a support wheel 4.

[0034] Specifically, Figure 3 As shown, the loading platform 1 is a frame structure formed by welding a number of steel pipes. It can not only ensure the load-bearing capacity of the loading platform 1, but also reduce the weight of the transport vehicle. More specifically, the loading platform 1 is made of 13 steel pipes welded flat to form a double "eye" shaped structure. The welding method of the surrounding steel pipes is electric welding, and the welding method of the internal steel pipes is fillet welding, ensuring that the welded loading platform 1 is strong and reliable.

[0035] Among them, Figure 1 and Figure 2As shown, the track wheel assembly 2 is provided with two sets and is symmetrically installed on the left and right sides below the front end of the loading platform 1. The track wheel assembly 2 includes a wheel bracket 21 and a wheel body 22. The wheel bracket 21 is fixed below the loading platform 1, and the wheel body 22 is installed on the wheel bracket 21. The two wheel bodies 22 are used to support the top of the left and right groove walls of the cable trench when traveling.

[0036] It is easy to understand that the track wheel assembly 2 not only plays a role in rolling travel, but also plays a role in bearing the weight of the front half of the trolley.

[0037] It should be noted that the direction of the vehicle's travel is "front", the forward direction is "rear", and the two sides are "left and right".

[0038] Specifically, the wheel bracket 21 is a U-shaped plate, the belly of the U-shaped plate is fixed to the lower surface of the loading platform 1, and the two wing plates of the U-shaped plate are inverted isosceles trapezoidal plates.

[0039] More specifically, the shaft of the wheel body 22 is inserted into the bottom ends of the two wings of the U-shaped plate and fixed by nuts, and the wheel body 22 is rotatably mounted on the shaft.

[0040] It is easy to understand that the track wheel is a wheel structure that can be limited on the supporting surface. No matter whether the trolley turns left or right, the track wheel cannot move outward or inward from the cable trench, thereby ensuring stable operation and reducing safety risks.

[0041] Specifically, the wheel body 22 includes a relatively fixed large-diameter wheel 221 and a small-diameter wheel 222, the large-diameter wheels 221 of the two wheel bodies 22 are opposite, and the distance between the small-diameter wheels 222 of the two wheel bodies 22 is adapted to the groove width of the cable groove. When traveling, the circumferential surface of the small-diameter wheel 222 is rolled and supported on the top surface of the groove wall of the cable groove, and the bottom of the large-diameter wheel 221 is placed on the inner side of the cable groove to play a limiting role.

[0042] It should be noted that the spacing between the small diameter wheels 222 of the two wheel bodies 22 is the spacing between the large diameter wheels 221 of the two wheel bodies 22 plus the width of the two large diameter wheels 221, and the spacing between the small diameter wheels 222 is adapted to the groove width of the cable groove, that is, the spacing between the small diameter wheels 222 is slightly smaller than the groove width of the cable groove to avoid friction between the wheel body 22 and the groove wall. For example, the groove width of the prefabricated groove adapted in this embodiment is 500mm, the diameter of the large diameter wheel 221 is 100mm and the width is 15mm, the diameter of the small diameter wheel 222 is 50mm and the width is 40mm, and a gap of 10mm is reserved between the large diameter wheel 221 of the wheel body 22 and the groove wall on the corresponding side, then the spacing between the small diameter wheels 222 should be designed to be 500-2×10=480mm, and the spacing between the large diameter wheels 221 should be designed to be 500-2×15-2×10=450mm.

[0043] Specifically, the wheel body 22 is a nylon wheel. Compared with a steel wheel, a nylon wheel can prevent the upper edge of the cable trench from being damaged during transportation by the trolley.

[0044] The support frame 3 is fixed at the lower middle part of the rear end of the loading platform 1; the support wheel 4 is installed at the bottom of the support frame 3, and the support wheel 4 is used to support the bottom of the cable trench when traveling.

[0045] It is easy to understand that the support frame 3 is located in the middle of the lower rear end, and the middle refers to the left and right direction. The purpose is to enable the support wheel 4 to be placed inside the cable trench, so as to be supported on the bottom of the cable trench.

[0046] Specifically, the support frame 3 includes two support arms 31 which are arranged vertically and distributed opposite to each other left and right, and the support wheel 4 is installed between the bottoms of the two support arms 31 .

[0047] More specifically, a wheel axle 32 is fixed between the bottoms of the two support arms 31, and the support wheel 4 is mounted on the wheel axle 32 through a bearing. Of course, the support wheel 4 can also be fixedly sleeved on the wheel axle 32, and then the wheel axle 32 is rotated to install the bottom of the support arm 31.

[0048] In detail, the support arm 31 is made of a steel pipe of appropriate strength, and the lower end of the steel pipe is flattened and punched. The flattening is to use nuts to fasten the wheel axle 32, and the drilling is to install the wheel axle 32.

[0049] It should be noted that the supporting wheel 4 adopts a single-wheel design, which can reduce the footprint of the trolley in the cable trench on the one hand, and facilitate the adjustment of direction on the other hand.

[0050] In addition, if Figure 1 and Figure 2 The concrete precast trough transport trolley of this embodiment further includes a handle 5, which is arranged at the rear end of the loading platform 1. The operator holds the handle 5 to facilitate pushing the trolley forward.

[0051] Specifically, the handle 5 includes two handrails 51 that are relatively distributed on the left and right sides. The two handrails 51 are located between the two sets of track wheel assemblies 2 in the left and right directions. The front ends of the handrails 51 are fixed to the rear ends of the loading platform 1, and the rear ends of the handrails 51 are tilted downward.

[0052] like Figure 4 and Figure 5 As shown, the working principle of the concrete precast trough transport trolley of this embodiment is as follows:

[0053] When in use, first place the trolley in the completed cable trench, so that the circumferential surfaces of the small-diameter wheels 222 of the two wheel bodies 22 are in contact with the upper edge of the cable trench, and the large-diameter wheels 221 are naturally placed in the cable trench, and the supporting wheels 4 are supported on the bottom of the cable trench. Then the precast concrete trough to be transported is placed on the loading platform 1, and then the construction personnel hold the handle 5 and push the trolley forward. When it reaches the destination, the precast concrete trough is removed from the loading platform 1 for construction.

[0054] The above is only a specific implementation of the utility model, so that those skilled in the art can understand or implement the utility model. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
