Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to a bridge auxiliary operation trolley suitable for complex terrain. Background Art

[0002] During the operation of the bridge deck's outer railings, foundation beams and other ancillary facilities, an open surface will be generated, so workers need to use an operation trolley to operate in these areas. However, when the operation trolley needs to operate on complex terrain (such as municipal bridges, which are usually equipped with sidewalks and have multiple ground beams on the side of the sidewalk, making the ground conditions more complicated), it is impossible to drive to the edge of the bridge to operate the bridge. For example, the patent with document number CN109763423A discloses an adjustable detachable mobile hanging basket for bridge maintenance and its operation method. By extending the connecting beam in the operation trolley and allowing workers to stand on the extended connecting beam to process the bridge, the connecting beam may be subjected to excessive pressure, resulting in fracture of the connecting beam, which brings inconvenience to the workers.

[0025] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0026] like Figure 1-5 As shown, the embodiment of the present utility model provides a bridge-attached operation trolley suitable for complex terrain, which can be used to construct anti-collision beams on the outer side of highway bridges with sidewalks. The bridge-attached operation trolley includes a trolley body 1, a connecting frame 3 and an operating platform 2 (taking into account that the operating platform 2 needs to bear the weight of the staff, and taking into account the manufacturing cost and lightweight requirements of the operating platform 2, in one embodiment, the bottom of the operating platform 2 is composed of a plurality of steel bars arranged at equal distances, and a steel mesh with a diameter of 60 mm is laid on the plurality of steel bars), the connecting frame 3 is fixedly arranged on one side of the trolley body 1, and the operating platform 2 is liftably installed on the end of the connecting frame 3 away from the trolley body 1, and the operating platform 2 is used to carry the staff so that the staff can stand on the operating platform 2 to operate the bridge;

[0027] Two sets of support legs 4 are vertically provided at the bottom of the trolley body 1, and each set has at least two support legs 4. The two sets of support legs 4 are respectively provided at one end of the trolley body 1 close to the operating platform 2 and the other end away from the operating platform 2. Heavy-duty universal wheels 5 are installed at the bottom of the support legs 4 for the trolley body 1 to slide on the bridge deck.

[0028] Taking into account the conventional height of the ground beam on the bridge deck during road and bridge construction, as the main improvement of the present invention, the length of the support leg 4 is ≥450mm, thereby ensuring that the bottom of the trolley body 1 has sufficient ground clearance, so that the trolley body 1 can move across the ground beam.

[0029] Taking into account the manufacturing cost and lightweight requirements of the trolley body 1, in one embodiment, the trolley body 1 is assembled into a frame structure by steel sections.

[0030] Specifically, the trolley body 1 includes two sets of frame-shaped support frames 11 and a plurality of connecting beams 12 fixedly connected between the two sets of support frames 11. Figure 3As shown, the support frame 11 includes a supporting longitudinal beam 111 and a supporting cross beam 112. The supporting cross beam 112 and the supporting longitudinal beam 111 together form a frame. In an improved embodiment, a first reinforcing beam 113 is cross-arranged in the frame structure formed by the supporting cross beam 112 and the supporting longitudinal beam 111, thereby enhancing the structural stability of the support frame 11.

[0031] The connecting frame 3 includes two connecting beams 31 and multiple fixed beams 32 fixedly connected between the two connecting beams 31. One end of the connecting beam 31 is detachably connected to the operating platform 2, and the other end of the connecting beam 31 is fixedly connected to the trolley body 1. The fixed beam 32 is used to strengthen the structural stability of the connecting frame 3. Considering that the operating platform 2 needs to carry staff during road and bridge construction, in order to further enhance the stability of the connecting frame 3, a second reinforcing beam 33 is obliquely provided at the bottom of the connecting beam 31. The trolley body 1, the connecting beam 31 and the second reinforcing beam 33 form a triangle.

[0032] Taking into account the width of the ground beam on the bridge deck and the distance between the ground beam and the side of the bridge during road and bridge construction, in order to make the support frame 11 better adapt to the working conditions, in a specific embodiment, the distance between the two sets of support legs 4 at the bottom of the trolley body 1 is greater than or equal to 3000mm.

[0033] In order to realize the lifting and lowering of the operating platform 2 and facilitate the installation of the operating platform 2, in a specific embodiment of the present invention, at least two mounting rods 21 are provided on the operating platform 2, and each mounting rod 21 is longitudinally opened with a plurality of connecting holes 22, and the connecting frame 3 is provided with a pin 34 for fixing the operating platform 2. Therefore, as a preferred embodiment of the present invention, the multiple connecting holes 22 on each mounting rod 21 are arranged at equal distances.

[0034] Taking into account that the trolley may not move along the ground beam during movement, and considering that the trolley body 1 is mainly pushed by manpower and the direction cannot be accurately controlled during movement, which may cause the support leg 4 to collide with the ground beam and deform, as a preferred embodiment of the present invention, the support leg 4 is provided with a directional wheel 6 on the side facing the middle of the trolley body 1, so as to avoid the support leg 4 from directly colliding with the ground beam. In addition, with the help of the directional wheel 6, the operator can also push the trolley body 1 close to the ground beam, and push the trolley body 1 to move when the directional wheel 6 contacts the ground beam. The ground beam is used to provide guidance for the movement of the trolley body 1, thereby saving the operator's physical strength and ensuring the stability of the moving path of the trolley body 1.

[0035] Taking into account that the bridge-attached work trolley for complex terrain provided by the utility model has a large span, and the operating platform 2 will bear the weight because of the standing staff, in order to avoid the tilting phenomenon due to the large difference in weight between the two ends of the support frame 11, as a preferred embodiment of the utility model, a load-bearing frame 7 is formed on the side of the support frame 11 away from the operating platform 2, and a counterweight block can be placed on the load-bearing frame 7, so that the support frame 11 will not be unbalanced in weight at both ends of the support frame 11 due to the weight borne by the operating platform 2, thereby causing the support frame 11 to tilt.

[0036] In summary, the bridge-attached work trolley suitable for complex terrain can cross complex ground conditions through the provision of support legs 4 without extending the length of the connecting frame 3.

[0037] The above-described embodiments merely represent implementation methods of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
