Fig. 1 and 2 show a crash truck for a guardrail according to the present application, wherein a working accessory 2 for a guardrail pile is arranged in the middle of a frame 1, that is, the working accessory 2 for the guardrail pile is arranged at the approximate middle position of the frame 1 along the longitudinal direction and the transverse direction of the frame 1, a turning device 5 is further arranged between the working accessory 2 for the guardrail pile and the frame 1 for the working accessory 2 to rotate on the frame 1, wherein the turning device 5 is a turning member, a pile driving part is arranged on the working accessory 2 for the guardrail pile 72 to perform pile driving operation, and the pile driving part 23 comprises a hydraulic hammer 222.
In a preferred embodiment, the guardrail pile working attachment 2 is a multi-functional device incorporating a hydraulic hammer 222, a drilling section 223 and a pile pulling section 224, as shown in figure 1, to achieve the functions of driving, drilling and pulling a pile in one device.
More specifically, referring to fig. 1, the guardrail pile working accessory 2 includes a fixing frame 21, a lifting rail 20 and a hydraulic hammer assembly 22, the fixing frame 21 is fixed on the revolving device 5, the hydraulic hammer assembly 22 is slidably disposed on the lifting rail 20, wherein the hydraulic hammer assembly 22 mainly includes a hydraulic hammer clamping plate 221, a hydraulic hammer 222, a drilling component 223 and a pile pulling component 224, and the hydraulic hammer 222, the drilling component 223 and the pile pulling component 224 are all fixed on the hydraulic hammer clamping plate 221.
It should be noted that the related hydraulic transmission system of the guardrail pile working accessory 2 is the prior art, and the specific implementation can refer to a guardrail pile working accessory disclosed in patent No. CN210946810U, or can refer to patent No. CN2498025Y and patent No. CN 201002549Y.
Because the whole length of the guardrail pile working accessory 2 is too long, the guardrail pile working accessory 2 needs to be turned to a stop position by the turning device 5 during transportation or stop, and the guardrail pile working accessory 2 is turned to a working position by the turning device 5 when the guardrail pile working accessory 2 needs to be used. Fig. 1 shows the guardrail pile working attachment 2 in the parking position, and fig. 4, 5 show the guardrail pile working attachment 2 in the working position. It will be understood that the parking position is the position in which the telescopic guide 27 of the guardrail pile working attachment 2 is in a direction substantially parallel to the direction of the vehicle frame 1; the working position is a position where the direction in which the telescopic rail 27 of the guardrail post working attachment 2 is located is substantially perpendicular to the direction of the vehicle frame 1.
Figure 6 shows the arrangement of the drive means of a conventional bollard working attachment 2. One end of the telescopic oil cylinder 23 is hinged with the fixed frame 21, the other end is hinged with the telescopic guide rail 27, the telescopic guide rail 27 is mounted on the fixed frame 21 in a manner of moving back and forth, the telescopic guide rail 27 is further hinged with the lifting guide rail 20, and one end of a support frame 28 is fixedly connected with the telescopic guide rail 27. One end of the supine oil cylinder 24 is hinged with the supporting frame 28, and the other end is hinged with the lifting guide rail 20 through a piston rod thereof. The hydraulic hammer assembly 22 is installed on the lifting guide rail 20, the lifting oil cylinder 25 and the supporting oil cylinder 26 are both fixed on the lifting guide rail 20, and are arranged on the same straight line, namely, the bottoms of the cylinder sleeves of the lifting oil cylinder 25 and the supporting oil cylinder 26 are fixedly connected with each other, and the extending directions of the piston rods of the lifting oil cylinder and the supporting oil cylinder are on the same straight line and opposite in direction. The piston rod of the lift cylinder 25 is used for driving the hydraulic hammer assembly 22 to move on the lift guide rail 20, and the piston rod of the support cylinder 26 is used for driving the support part 29' to move up and down to support the ground.
It will be appreciated that the stroke through which the hydraulic hammer assembly 22 can move is determined by the stroke of the lift cylinder 25, and that the greater the stroke of the cylinder, the greater the length of the corresponding piston rod, cylinder barrel, and thus the overall length of the cylinder. Therefore, the greater the required stroke of hydraulic hammer assembly 22, the greater the overall length of lift cylinder 25, and likewise, the greater the required stroke of support member 29, the greater the overall length of support cylinder 26.
The drive arrangements of the guardrail pile working attachment 2 shown in fig. 6, in particular with regard to the arrangement of both the lift cylinders 25 and the support cylinders 26 in line within the lift rail 20, result in the overall length of the lift rail 20 being required to simultaneously meet the length of both the lift cylinders 25 and the support cylinders 26.

Simultaneously, because the motorcycle type that traditional guardrail breakdown van was compared to the motorcycle type that this application needs chooseed for use is bigger, still add between slewer 5 and frame 1 in addition and move the mechanism 8 by indulging, it can be higher to lead to whole guardrail stake work accessory 2 its height of arranging to can lead to, when guardrail stake work accessory 2 carries out the pile pulling, the required displacement distance that the support component reachd ground is just bigger, thereby support cylinder 26's whole length also can be longer.
In the above case, the arrangement of the drive means of the conventional guardrail pile working attachment 2 as shown in fig. 6 causes at least the following problems: 1. the lifting guide rail 27 being too long can interfere with other devices on the frame 1, especially when the guard rail pile working attachment 2 is in a stop position; 2. the length of the lifting rail 27 of the guardrail pile working attachment 2 is increased, particularly the length of the support cylinder 26 is increased, which causes the overall center of gravity of the lifting rail 27 to be shifted further to the lower end, which is not favorable for the arrangement and use of the lifting rail 27. Therefore, it is necessary to shorten the entire length of the lifting rail 27, which is advantageous not only for the arrangement of the lifting rail 27 but also for the center of gravity of the lifting rail 27 to be more close to the position where it is carried by the fixed frame 21.
Fig. 7 illustrates an example of an improved structure of a driving apparatus, and it should be noted that fig. 7 removes a portion of the lift rail 20 in order to facilitate the observation of the lift cylinder 25 disposed in the lift rail 20.

The support cylinder 26 is disposed on the rear surface of the elevation rail 20 in parallel with respect to the elevation cylinder 25, and a piston rod of the support cylinder 26 is used to drive the support member 29. The overall length of the lift rail 20 thus only needs to be the same as the overall length of the lift cylinder 25, no longer the length of the support cylinder 26, and no longer the length of additional support members. More specifically, referring to fig. 7 and 8, the piston rod of the lift cylinder 25 is connected to a rolling frame 201, the rolling frame 201 is fixedly connected to the hydraulic hammer assembly 22, the rolling frame 201 is symmetrically provided with a plurality of first rollers 2011 and a plurality of second rollers 2012 on both sides thereof, wherein the first rollers 2011 roll on the side surfaces of the lift rail 20, and the second rollers 2012 roll between the bottom surface and the top surface of the lift rail 20, so that the lift cylinder 25 can drive the rolling frame 201 and the hydraulic hammer assembly 22 to move on the lift rail 20.
In a preferred embodiment, when the piston rod of the support cylinder 26 is at the initial position, which is the position where the piston rod is not extended outward, and the piston is at the bottom of the cylinder, the lower end surface of the support member 29 is flush with the lower end surface of the lifting rail 20, so that the support cylinder 26 and the support member 29 do not increase the overall length of the guardrail pile working tool 2, and the required travel of the support member 29 to the ground is minimized. It will be appreciated that when the lower end face of the support member 29 exceeds the lower end face of the lifting rail 20, the support member 29 will provide an additional increase in the overall length of the guardrail pile working attachment 2; when the lower end surface of the lift rail 20 exceeds the lower end surface of the support member 29, the stroke required for the support member 29 to reach the ground is greater, and the support cylinder 26 is longer.
In order to stabilize the guard bar pile working accessory 2 during working and avoid long-time heavy pressure on automobile tires when a guard bar breakdown van is stopped at a station, a supporting device is arranged below the frame 1, specifically, a plurality of hydraulic supporting legs 80 are arranged below the frame 1, and the hydraulic supporting legs 80 are put down when the guard bar pile breakdown van is stopped at the station and the guard bar pile working accessory 2 works.
The terms of orientation of up, down, left, right, front, back, top, bottom, and the like referred to or may be referred to in this specification are defined relative to the configuration shown in the drawings, and are relative terms, and thus may be changed correspondingly according to the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms.
It should be understood that all of the above preferred embodiments are exemplary and not restrictive, and that various modifications and changes in the specific embodiments described above, which would occur to persons skilled in the art upon consideration of the above teachings, are intended to be within the scope of the invention.
