Steel bar supporting trolley

Abstract

The utility model provides a reinforcing steel bar supporting trolley which comprises a frame sleeved on a guide rail, a bearing roller contacted with the guide rail is arranged at the bottom of a panel of the frame, a supporting rod is hinged on the panel of the frame, and a supporting spring is arranged between the supporting rod and the panel. Due to the fact that the bottom of the panel of the frame is provided with the bearing idler wheels in contact with the guide rail, the weight of the frame and the weight of parts borne by the frame act on the guide rail through the idler wheels, the trolley can smoothly pass through even if sliding for a long distance or sliding to the connecting position or the concave-convex position of the guide rail, the situation of blocking or stopping cannot happen, and using of workers is convenient.

Description

TECHNICAL FIELD

[0001] The utility model relates to the field of steel bar hoop bending machine, especially the supporting structure of long steel bar bending. BACKGROUND

[0002] The prior art double-hoop steel bar hoop bending machine can bend the two ends of the steel bar at the same time, improving the production efficiency. However, when the bending machine bends the long steel bar, the middle part of the steel bar will be concave downward, forming an arc-shaped depression, which will affect the bending precision and shape of the steel bar. Therefore, the technical personnel often set up a supporting structure between the two hoop heads. Most of the current supporting structures are supporting trolleys, and the structures of the trolleys are various, but they generally cannot move long distances, especially at the connection of some racks or guide rails, which are easy to be stuck or stopped, and are not very convenient to use. SUMMARY

[0003] In view of the above shortcomings of the prior art, the utility model aims to provide a steel bar supporting trolley which can move long distances and is convenient to move.

[0004] The utility model realizes the above-mentioned purposes in the following way:

[0005] A steel bar supporting trolley comprises a frame sleeved on a guide rail, a load roller in contact with the guide rail is installed at the bottom of the panel of the frame, a supporting rod is hinged to the panel of the frame, and a supporting spring is installed between the supporting rod and the panel.

[0006] The bottom of the side plate of the frame is provided with a roller in contact with the bottom surface of the guide rail.

[0007] The rollers are four in number and two on each side plate, and are symmetrically arranged.

[0008] The middle part of the side plate of the frame is provided with a roller in contact with the side surface of the guide rail.

[0009] The rollers are four in number and two on each side plate, and are symmetrically arranged.

[0010] The rollers are installed on the frame through respective shaft bodies.

[0011] The supporting rod is hinged to two fixed blocks on the panel, and a stopper limiting the rotation of the supporting rod in the direction opposite to its gravity is fixed to the upper part of the fixed block.

[0012] The utility model has the advantages that the load roller in contact with the guide rail is installed at the bottom of the panel of the frame, the weight of the frame and the components carried by the frame is applied to the guide rail through the load roller, even if the trolley slides long distances or reaches the connection or concave-convex place of the guide rail, it can still smoothly pass through without being stuck or stopped, which is convenient for workers to use. BRIEF DESCRIPTION OF DRAWINGS

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0014] Figure 1 This is a three-dimensional structural diagram of the present invention. Detailed Implementation

[0015] Reference Figure 1 A rebar support trolley includes a frame 2 fitted onto a guide rail 1. A load-bearing roller 3, in contact with the guide rail 1, is mounted on the bottom of the frame 2's panel. A support rod 4 is hinged to the panel of the frame 2, and a support spring 5 is installed between the support rod 4 and the panel. Because the load-bearing roller 3 is mounted on the bottom of the frame 2's panel, the weight of the frame 2 and its supported components is transferred to the guide rail 1 through the roller 3. Even if the trolley travels a long distance or slides to the joints or uneven areas of the guide rail 1, it can pass smoothly without jamming or stopping, facilitating worker use. The support spring 5 cushions the weight of the supporting rebar, ensuring that the hinge of the support rod 4 is not easily damaged by gravitational impact.

[0016] The bottom of the side plates of the frame 2 is equipped with rollers 3 that can contact the bottom surface of the guide rail 1. When the support rod is carrying reinforcing bars, the entire support trolley will tend to tilt outwards. At this time, the rollers 3 in contact with the bottom surface of the guide rail 1 can effectively prevent the entire support trolley from tipping over. This method is simpler and more effective than relying solely on the side plates of the frame to prevent tipping. There are four rollers 3, two on each side plate, arranged symmetrically, which further effectively prevents the support trolley from tipping over in any direction.

[0017] In addition, to reduce friction between the frame side plates and the guide rail 1 when the support trolley moves, and to facilitate the movement of the support trolley, rollers 3 that can contact the side of the guide rail 1 are installed in the middle of the side plates of the frame 2. There are four rollers 3, two on each side plate, arranged symmetrically, thereby further ensuring that the support trolley moves smoothly and conveniently along the direction of the guide rail 1.

[0018] To reduce interference between the rollers, each roller 3 is mounted on the frame 2 via its own shaft 6.

[0019] Furthermore, the support rod 4 is hinged to two fixed blocks 7 on the panel, and a stop block 8 is fixed on the upper part of the fixed block 7 to restrict the support rod 4 from rotating in the opposite direction of its gravity. This is to prevent workers from removing the steel bars from the support rod 4 and rotating them upwards, which could cause safety accidents such as injuring workers.
