Technical Field

[0001] This utility model relates to a lifting bridge, and more particularly to a hydraulic lifting bridge for engineering machinery, belonging to the field of lifting bridge technology. Background Technology

[0002] A hydraulic lift bridge is a type of engineering machinery that lifts the bridge body to allow ships to pass in a timely manner.

[0003] In the prior art, such as the Chinese authorized patent CN202120033543.9, a hydraulic lifting bridge for engineering machinery, the bridge body is lifted and fixed by the cooperation of a motor, rotating shaft, gear, rack plate, connecting plate, first movable rod, moving plate, second movable rod and clamping plate, which improves the fixing effect of the bridge body and thus greatly improves the stability of the bridge body, prevents the bridge body from slipping after being lifted, and prevents it from causing great safety hazards to passing ships. This solves the problem of poor bridge body fixing effect of traditional hydraulic lifting bridges for engineering machinery.

[0004] However, using a clamping plate for fixing can lead to the bridge body being heavy, which can cause the clamping slot to loosen over time. Furthermore, accurate alignment is required for precise clamping, and inaccurate clamping may occur after prolonged use. Utility Model Content

[0005] The main purpose of this utility model is to solve the problem that the slot position is prone to loosening after long-term use, and that accurate alignment is required for precise locking. In this case, the locking will become inaccurate after long-term use. Therefore, this utility model provides a hydraulic lifting bridge for engineering machinery.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A hydraulic lifting bridge for engineering machinery includes two supports and a fixed plate installed on the upper end of the supports. Two hydraulic telescopic rods are arranged below the fixed plate. The output end of the hydraulic telescopic rods is equipped with a bridge body. Assembly slots are opened on the two supports. A first fixing component is installed in the assembly slot. A second fixing component is arranged above the first fixing component.

[0008] Furthermore, a reinforcing plate is installed at the lower end of the bridge body.

[0009] Furthermore, slots are provided at both ends of the bridge body.

[0010] Furthermore, the first fixing component includes a mounting plate and a first electric push rod mounted on the mounting plate, the output end of the first electric push rod being fitted with a locking block.

[0011] Furthermore, the upper outer wall of the card block is rotatably connected with several rollers.

[0012] Furthermore, the upper part of one end of the card block is provided with an arc-shaped chamfer.

[0013] Furthermore, an extension plate is provided at the other end of the card block.

[0014] Furthermore, a base plate is installed at the lower end of the bracket.

[0015] Furthermore, the second fixing component includes a second electric push rod and a locking plate mounted on the output end of the second electric push rod.

[0016] Furthermore, the height of the card plate is less than the height of the card slot.

[0017] The beneficial technical effects of this utility model are as follows: According to the hydraulic lifting bridge of this utility model, the bridge body is pulled upward to the designated position by two hydraulic telescopic rods installed below the fixed plate. The first electric push rod in the first fixed component pushes the locking block outward, so that it can be supported under the reinforcing plate at the bottom of the bridge body. At the same time, multiple rollers can reduce friction and improve service life. In conjunction with the second fixed component, the bridge body is fixed secondary from the side wall to improve the safety factor. Attached Figure Description

[0025] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0026] like Figures 1-6 As shown, the hydraulic lifting bridge for engineering machinery provided in this embodiment includes two supports 1 and a fixing plate 2 installed on the upper end of the supports 1. Two hydraulic telescopic rods 5 are arranged below the fixing plate 2. The output end of the hydraulic telescopic rods 5 is equipped with a bridge body 3. Assembly slots 16 are opened on the two supports 1. A first fixing component 6 is installed in the assembly slot 16. A second fixing component 7 is arranged above the first fixing component 6. A reinforcing plate 8 is installed at the lower end of the bridge body 3. Both ends of the bridge body 3 are provided with slots 9. The first fixing component 6 includes a mounting plate and a first electric push rod 12 installed on the mounting plate. A locking block 10 is installed at the output end of the moving push rod 12. Several rollers 11 are rotatably connected to the upper outer wall of the locking block 10. A rounded chamfer is provided at the upper part of one end of the locking block 10, and an extension plate 13 is provided at the other end of the locking block 10. A base plate 4 is installed at the lower end of the bracket 1. The second fixed component 7 includes a second electric push rod 15 and a locking plate 14 installed on the output end of the second electric push rod 15. The height of the locking plate 14 is set to 10cm, and the height inside the slot 9 is 15cm, so that the locking plate 14 does not contact the side wall of the slot 9, avoiding friction. As a secondary protective component, it improves safety.

[0027] The bridge body 3 is pulled upward to the designated position by two hydraulic telescopic rods 5 installed below the fixed plate 2. The first electric push rod 12 in the first fixed component 6 pushes the locking block 10 outward so that it can be supported under the reinforcing plate 8 at the bottom of the bridge body 3.
