Detailed Description
In order to make the person skilled in the art better understand the solution of the present utility model, the following describes the solution of the present utility model with reference to specific embodiments.
Referring to fig. 1-2, a double-bracing car bracing device comprises a transverse frame 1, a connecting shaft 2, a first support kick 3, a second support kick 4, a first draw hook 5, a second draw hook 6, a first tension spring 7 and a second tension spring 8.
The transverse frame 1 is used as a bearing foundation of the whole double-support car support device, and is fixed on a car body through bolts when in use, and specifically, the transverse frame 1 comprises a top plate 1.1 and side supporting walls 1.2 arranged on two sides of the top plate, and mounting holes 1.3 are further formed in the top plate 1.1 and are used for being fixed with the car body.
Through holes for mounting the connecting shaft 2 are symmetrically provided on the two side support walls 1.2, and the connecting shaft 2 is transversely penetrated therein so that the connecting shaft 2 can rotate in the through holes.
The first supporting kicker 3 is installed at one end of the connecting shaft 2 and is located at the outer side of the lateral supporting wall 1.2, specifically, the top of the first supporting kicker 3 is provided with a pin a, the pin a is perpendicular to the first supporting kicker 3, and the first supporting kicker 3 is installed at one end of the connecting shaft 2 through the pin. Similarly, the second supporting leg 4 is mounted at the other end of the connecting shaft 2, specifically, a pin is also arranged at the top of the second supporting leg 4, the pin and the second supporting leg 4 are vertically arranged, and the second supporting leg 4 is mounted at the other end of the connecting shaft 2 through the pin.
On the top plate 1.1 of the cross frame 1, a first mounting shaft b1 and a second mounting shaft b2 are symmetrically arranged, and the two mounting shafts are positioned on the front side (relative to the vehicle body) of the top plate 1.1 and positioned at two ends of the top plate 1.1, wherein the first mounting shaft b1 is positioned on one side close to the first supporting kick 3, and the second mounting shaft b2 is positioned on one side close to the second supporting kick 4; the top of the first draw hook 5 is arranged on the first installation shaft b1, and the top of the second draw hook 6 is arranged on the second installation shaft b 2.
The bottom of the first drag hook 5 is connected with the first supporting kick 3 through a first tension spring 7, and the bottom of the second drag hook 6 is connected with the second supporting kick 4 through a second tension spring 8.
Further, a front guide wall 1.21, a rear guide wall 1.22 and a limit protrusion 1.23 are arranged on the lateral support wall 1.2 of the transverse frame 1, wherein the limit protrusion 1.23 is positioned at the rear side of the top of the support kick in a falling support state (the rear side is relative to the car body, namely the tail of the car body is in the rear side direction, and the front of the car body is in the front side direction) and is used for limiting the support kick to continue to rotate forwards so as to make the support kick stable in a support state; the front guide wall 1.21 is gradually bent outwards from top to bottom, the rear guide wall 1.22 is gradually bent inwards from front to back upwards, when the support kick is lifted backwards, under the guide action of the front guide wall 1.21 and the rear guide wall 1.22, the support kick can be lifted backwards smoothly and the two support kicks converge inwards in the lifting process, so that when the first support kick and the second support kick are in a supporting state, the support kick is splayed, the distance between the support points on two sides of the vehicle body is large enough, and the stability of supporting the vehicle body is improved; when the first support kicks and the second support kicks are lifted, the first support kicks and the second support kicks can be retracted inwards, so that the transverse occupied space of the first support kicks and the second support kicks is reduced.
Further, when the first supporting kick and the second supporting kick are in the lifted state, the two supporting kicks can be kept in the lifted state under the action of the first tension spring 7 and the second tension spring 8. Referring to fig. 3, in fig. 3, O1 is the axis of the mounting shaft on the transverse frame, O2 is the axis of the connecting shaft 2, L1 represents the length of the tension spring in the supporting state of the supporting kick, L3 represents the length of the tension spring in the lifting state of the supporting kick, L2 represents the maximum length of the tension spring in the lifting/supporting switching process of the supporting kick, and it can be seen that the length of L2 is greater than L1 and L3, that is, the tension force of the tension spring in the lifting/supporting switching process of the supporting kick is greater than the tension force of the tension spring in the lifting state and the supporting state of the supporting kick, so that when the tension spring moves from the L2 position to the L1 position, the tension spring can provide the falling tension force for the supporting kick, and when the tension spring moves from the L2 position to the L3 position, the tension spring can also provide the lifting tension force for the supporting kick, thereby improving the smoothness of the lifting/supporting state of the supporting kick.
Further, the first hook 5 and the second hook 6 are in a hook shape, and the caliber of the hook is larger than the diameter of the connecting shaft 2, so that when two supports are kicked backward (relative to the vehicle body), the bottom ends of the first hook 5 and the second hook 6 can move to the rear side position below the connecting shaft 2, and therefore the movement of the first tension spring 7 and the second tension spring 8 is not affected, that is, if the first hook 5 and the second hook 6 are not provided, the connecting shaft 2 can block the movement of the first tension spring 7 and the second tension spring 8 when the two supports are kicked backward.
