Abstract
The utility model discloses a road and bridge load-limiting protection device comprising a support rack, a press plate, a support plate and at least one spring. The spring is fixedly mounted in the support rack. The side wall of the support rack can be rotationally connected to one side of the press plate, and the other side of the press plate is located on the spring. The support plate can be rotationally connected at the bottom surface of the press plate. The road and bridge load-limiting protection device has the advantages that the entire structure is simple and reliable, and assembling and constructing are facilitated; overloaded vehicles are effectively prevented from driving on roads and bridges to prevent the same from being damaged, and manual management and power are omitted; and the load-limiting protection can be cancelled in an emergency, and accordingly, the road and bridge load-limiting protection device is convenient to use.
Description
Technical field
The utility model relates to a kind of road and bridge protective device, particularly a kind ofly limits load-carrying with the protection protective device of road and bridge.
Background technology
At present, because causing road and bridge, the problems such as overload of vehicle spreading damage, the phenomenon that major accident even occurs happens occasionally, for fear of similar accident occurring, in some road and bridge engineering, for the vehicle of avoiding surpassing the bridge rated load is gone up bridge by force, bridge is caused damage, adopt the measures such as height-limiting bar, limit the gross weight of vehicle by the height of restriction vehicle loading goods, but due to the difference of institute's cargo, the method is limiting overload of vehicle well, and occurs often that height-limiting bar is damaged and situation about losing efficacy.
The utility model content
The purpose of this utility model is customer service the deficiencies in the prior art and a kind of road and bridge load limit protective device simple and reliable for structure is provided.
For achieving the above object; the technical solution adopted in the utility model is: a kind of road and bridge described in the utility model load limit protective device; comprise support, pressing plate, gripper shoe and at least one spring; described spring is fixedly mounted in described support; one side of described pressing plate and the sidewall of described support are rotatably connected; the opposite side of described pressing plate is taken and is put on described spring, the described pressing plate bottom surface gripper shoe that is rotatably connected.
Further, described spring is a plurality of, and a plurality of described springs are laterally put with arranging.
Further, described pressing plate and the sidewall of described support are rotatably connected and are connected for bearing pin.
Further, described pressing plate and described gripper shoe are rotatably connected and are connected for bearing pin.
Further, described pressing plate is steel plate, and described support is steel bracket.
After adopting said structure; the utility model beneficial effect is: overall structure is simple and reliable; installation is also very simple and convenient; can effectively limit overloaded vehicle and reach road and bridge; to protect road and bridge not damaged, need not labor management, need not power disposition; can cancel the limit for tonnage protection when meeting emergency, the convenient use.
Description of drawings
Fig. 1 is the structural representation that the utility model is in the limit for tonnage protection;
Fig. 2 newly is in the not structural representation of limit for tonnage protection for this practicality.
Description of reference numerals:
1. support, 2. pressing plate, 3. bearing pin, 4. spring, 5 gripper shoes.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of road and bridge described in the utility model load limit protective device, comprise support 1, pressing plate 2, gripper shoe 5 and at least one spring 4, described spring 4 is fixedly mounted in described support, one side of described pressing plate 2 is connected by bearing pin 4 with the sidewall of described support 1, the opposite side of described pressing plate 2 is taken and is put on described spring 4, and described pressing plate 2 underrun bearing pins connect gripper shoe 5; Described pressing plate is steel plate, and described support is steel bracket.As described in Figure 2, by being fallen, gripper shoe 5 can cancel the limit for tonnage protection when meeting emergency.
The above is only better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
