Description
Technical Field
The utility model relates to an engineering vehicle and mobilizable protector thereof belongs to engineering vehicle accessory technical field.
Background
The engineering vehicle not only runs on urban roads, but also frequently runs on the construction site. When the automobile runs on an urban road, if the gap between the protection device and the ground is large, the risk that a pedestrian or a non-motor driver is drawn into the wheel and is rolled easily occurs. If the vehicle runs on the construction site, the protection device needs to be kept at a certain distance from the ground to avoid scraping and colliding with the ground due to the complex road condition of the construction site. Therefore, the requirements of the two different driving environments on the protection device can be extended and contracted up and down, and the safety, convenience and durability principles are required to be met.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art defect, provide one kind and can make protector stretch out and draw back from top to bottom, adapt to the engineering vehicle and the protector of the different environment of traveling.
In order to solve the technical problem, the utility model discloses a technical scheme does:
the utility model provides a mobilizable protector, includes fixed guardrail, the below of fixed guardrail is provided with movable guardrail, the back of fixed guardrail is provided with vertical fixed plate, be fixed with extending structure on the vertical fixed plate, extending structure's flexible end set up down and with movable guardrail links to each other, be provided with the uide bushing of vertical direction on the fixed guardrail back, be provided with the guide bar of vertical direction on the movable guardrail back, the upper end activity of guide bar passes the uide bushing.
The telescopic structure comprises an air cylinder or a hydraulic cylinder.
The number of the guide sleeves and the number of the guide rods are two.
The back of the vertical fixing plate is provided with a guardrail groove, and the telescopic structure is hidden in the guardrail groove.
The number of the vertical fixing plates and the number of the telescopic structures are two.
A movable protection device comprises the movable protection device.
The utility model has the advantages that: the utility model provides an engineering vehicle and mobilizable protector thereof, the uide bushing cooperation on the guide bar on the movable guardrail and the fixed guardrail ensures that the guardrail can only the up-and-down motion under extending structure's drive, effectively prevents the side striking, prevents that personnel from being drawn into inside the vehicle, ensures security, convenience, durability principle.
Drawings
Fig. 1 is a schematic view of a back structure of a movable guard of the present invention;
fig. 2 is a schematic side view of a movable guard according to the present invention.
The reference numbers in the figures are as follows: 1-fixing the guard bar; 2-vertical fixing plate; 3-a telescopic structure; 4-movable guard bar; 5, a guide sleeve; 6-guide rod.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, and the following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 and 2, the utility model discloses a mobilizable protector, including fixed guardrail 1, the below of fixed guardrail 1 is provided with movable guardrail 4, and the back of fixed guardrail 1 is provided with vertical fixed plate 2, is fixed with extending structure 3 on vertical fixed plate 2, and extending structure 3's flexible end sets up down and links to each other with movable guardrail 4, is provided with the uide bushing 5 of vertical direction on the 1 back of fixed guardrail, is provided with the guide bar 6 of vertical direction on the 4 backs of movable guardrail, and the uide bushing 5 is passed in the upper end activity of guide bar 6. The guide rod 6 on the movable guardrail 4 is matched with the guide sleeve 5 on the fixed guardrail 1, the movable guardrail 4 can only move up and down, the impact on the side surface has enough resistance strength, and the telescopic structure 3 is prevented from directly participating in stress.
The utility model discloses in, extending structure 3 includes cylinder or pneumatic cylinder.
The utility model discloses in, the number of uide bushing 5 and guide bar 6 is two, and the number of vertical fixed plate 2 and extending structure 3 is two.
The utility model discloses in, the back of vertical fixed plate 2 is provided with the guardrail recess, and extending structure 3 hides in the guardrail recess, and compact structure not only protects extending structure 3 moreover.
The utility model discloses a working method does: on an urban road, the telescopic structure 3 is in an extension state, and the position of the movable guardrail 4 away from the ground is lower; on the construction site, the telescopic structure 3 is in a contracted state, and the movable guardrail 4 is higher away from the ground.
The utility model discloses still disclose a mobilizable protector, including above-mentioned mobilizable protector.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
