Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

The first embodiment is as follows:

as shown in fig. 1, 2 and 3, the present embodiment provides a supporting leg cushion plate box, which includes a box body 1, wherein the box body 1 is a semi-open structure, and includes an inner cavity for accommodating the supporting leg cushion plate 4 and an opening 9 for storing the supporting leg cushion plate 4 in the inner cavity and/or taking out the supporting leg cushion plate 4 from the inner cavity, which are formed by an upper cover plate, a lower bottom plate, a rear baffle plate and side plates, and a partition plate 7 is disposed on the lower bottom plate, so that the box body 1 can allow two sets of supporting leg cushion plates 4 to be stored.

Be provided with stop gear on the box 1, including L template 2 and baffle 3,L template through welding or bolt assembly fix at the top of box 1, when adopting bolt assembly to fix, seted up the unthreaded hole on the L template 2 and accomplished fixedly in order to pass through the bolt. Baffle 3 is connected with L template 2 through round pin axle 5: specifically, the pin shaft 5 is provided with threads and polished surfaces with specific diameters and lengths, and can be matched with related components of the pin shaft 5 to realize connection between the baffle 3 and the L-shaped plate 2, and the pin shaft 5 is provided with two groups in order to avoid overlarge left-right shaking amount of the baffle 3 due to bumping of the concrete pump truck. Baffle 3 sets up in opening 9 department, and baffle 3 is used for spacing landing leg backing plate 4 of depositing in the inner chamber: specifically, the baffle 3 is provided with a chute 8 matched with the pin shaft 5, namely the outer diameter of the pin shaft 5 is not larger than the inner diameter of the chute 8, and the diameter of a flange at one end of the pin shaft 5 is larger than the inner diameter of the chute 8, so that the baffle 3 can only slide up and down in the shape of the chute 8 while not shaking; the sliding groove 8 is zigzag-shaped, in the embodiment, the sliding groove 8 is similar to a Z shape as shown in fig. 3, so that the baffle 3 cannot easily and freely slide up and down, only when the handle 6 arranged at the upper part of the baffle 3 is used to manually and dynamically lift the baffle 3 according to the shape of the sliding groove 8, the baffle 3 can be smoothly lifted to the opening position to relieve the limit of the baffle 3 at the opening 9, and the baffle 3 can automatically slide to the locking position under the action of self gravity after the handle 6 is released.

The working principle is as follows:

when the supporting leg base plate 4 needs to be used, one hand holds the handle 6 on the baffle plate 3, dynamic force is applied upwards according to the shape of the sliding groove 8, when the baffle plate 3 slides to the highest point, the other hand holds the handle 10 on the supporting leg base plate 4, the supporting leg base plate 4 can be taken out of the box body 1, after the supporting leg base plate 4 is taken out, the handle 6 is loosened, the baffle plate 3 can automatically slide to the lowest point by means of self gravity, and the operation of taking out the supporting leg base plate 4 is completed. When the supporting leg base plate 4 is stored, one hand grips the handle 10 on the supporting leg base plate 4, the other hand holds the handle 6 on the baffle plate 3, upward dynamic force is applied according to the shape of the sliding groove 8, when the baffle plate 3 slides to the highest point, the supporting leg base plate 4 is pushed to the bottom of the box body 1, the two hands are loosened, the baffle plate 3 automatically slides to the lowest point by means of self gravity, and the operation of storing the supporting leg base plate 4 is completed.

According to stop gear's structure and theory of operation explanation on above-mentioned box 1, it should be understood that, stop gear only remains baffle 3 and slides from top to bottom with the shape of spout 8, and all the other subassemblies are fixed state, have reduced the complicated cooperation connection or action between realizing spacing required actual work part and the multicomponent, consequently under the abominable operational environment of concrete pump truck, the utility model discloses a stop gear has extremely strong operational reliability, and the concrete expression does: as long as slide damper 3 about with handle 6 just can realize spacing and removing spacing to landing leg backing plate 4, the realization mode is high-efficient convenient, easy operation.

Example two:

the embodiment provides a concrete pump truck, including the automobile body, embodiment one is installed respectively to the both sides of automobile body the landing leg backing plate case to do not influence the balance of automobile body, deposit 2 landing leg backing plates 4 in every landing leg backing plate case, satisfy four landing leg backing plates 4 demands of general concrete pump truck.

To sum up, the utility model discloses simple structure, clean and tidy pleasing to the eye, the good reliability is applicable to the abominable operational environment of mobile concrete pump to access and spacing landing leg backing plate are high-efficient convenient, easy operation.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
