The main rod 2 of the collecting frame can also be fixedly provided with a second connecting piece 12; the other end of the spring 7 is hinged to the main collector frame rod 2 via a second connector, and the second connector may include: a rib plate and a sixth connecting rod; the other end of the spring 7 can be fixedly provided with a bearing, the rib plates can be two identical rib plates provided with through holes, the through holes of the sixth connecting rod and the two rib plates can be clamped by nuts, the inner wall of the bearing of the spring 7 and the part of the sixth connecting rod between the two rib plates are clamped, and the spring 7 can rotate through the bearing; the position of the sixth connecting rod can be assumed to be the hinge point C.

The connecting screw 5 can be articulated with the cylinder 3 via the guide block 9.
To further explain the present solution, the present application provides a specific application example of a current collecting frame, which specifically includes:
the device comprises a bearing seat, a cylinder bracket, a large arm cylinder, a connecting screw rod guide block, a connecting screw rod, a first rib plate, a second rib plate, a large arm and a spring; the cylinder support can be equivalent to the above-mentioned bracing piece, and big arm cylinder can be equivalent to above-mentioned cylinder, and connecting screw rod guide block can be equivalent to above-mentioned guide block, and big arm can be equivalent to above-mentioned collecting rack mobile jib.
The first rib plate is fixedly welded with the large arm; the second rib plate is fixedly welded with the large arm; the big arm and the bearing seat are fixed at a hinge point A (rotatable) through a shaft; the connecting screw rod and the first rib plate are fixedly (rotatably) connected with a hinge point B through a shaft; a screw rod at the right end of the spring is connected and fixed with a second rib plate at a hinge point C (rotatable) through a shaft C; the connecting screw rod is connected with the connecting screw rod guide block through threads, and the touch screen height can be adjusted (movable) through adjusting the fixing nut; the joint bearing at the right end of the large arm cylinder and the connecting guide block are fixedly connected with a hinge point D (rotatably) through a shaft D; the left end connector of the large arm cylinder is connected and fixed with a hinge point E (rotatable) through a shaft E with the cylinder bracket; the cylinder bracket and the bearing seat are assembled and fixed through a structure; the screw rod at the left end of the spring is connected and fixed with the bearing seat at a hinge point F (rotatable) through a shaft F1 and a shaft F2. The bearing seat, the cylinder bracket, the large arm cylinder, the connecting screw rod guide block, the connecting screw rod, the first rib plate, the second rib plate, the large arm and the outer wall of the spring can be provided with antirust coatings; the collector frame may further include a stabilizing base.
Specifically, as shown in fig. 6, the large arm can be raised by a spring, and the hinge point a: the connecting point of the large arm and the bearing seat; hinge point B: the spring is connected with the bearing seat; hinge point C: the spring is connected with the big arm. Due to the contractible capacity of the spring, the internal force of the spring can act on the tendency that the hinge point C is displaced towards the hinge point B. The spring pull on hinge point a may create a force component F1 (perpendicular to the line between hinge point a and hinge point C) and a force component F2 (along the line between hinge point a and hinge point C). Because the large arm between the hinge point A and the hinge point C is a rigid body (macroscopically undeformable), the component force F2 is changed into a large arm internal force; the component force F1 has a moment which drives the large arm to rotate counterclockwise relative to the hinge point A, and drives the large arm to rotate counterclockwise around the hinge point A, so that the large arm is lifted.
The height position change of the wire mesh can be compensated through the collector frame, for example, when the current collector is loaded and debugged, the height of the wire mesh is calibrated to be 5.5m, and the contact force between a carbon brush part of the collector head and the wire mesh is kept to be 120N.
If the downward pressure of the wire mesh on the carbon brush component of the collector head is removed, the spring tension has component force on the large arm to drive the large arm to rotate anticlockwise around the hinge point, so that the large arm can ascend, under the working condition that the large arm cylinder is not filled with gas, the rotatable limit position of the large arm, namely the piston rod of the large arm cylinder, is compressed to the shortest position, and the height of the large arm cylinder of the collector is 7 m.
If the height of the wire mesh is lower than 5.5m, the height of the contact position of the carbon brush of the collector head and the wire mesh is reduced, the large arm is driven to rotate clockwise around the hinge point of the large arm and the bearing seat, meanwhile, the spring extends, and the deformation is increased. The extension deformation of the spring can meet the requirement that the trolley pole falls to the position of the fixed tail hook, and can completely meet the requirement of small change or small height error on the height position of a wire mesh.
The present invention has been explained by using specific embodiments, and the explanation of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be changes in the specific embodiments and the application range, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
