Description

Technical Field

[0001] The utility model relates to the technical field of track wheel lifting, in particular to a track wheel lifting and mounting mechanism for a crawler type skid loader. Background Art

[0002] Crawler skid loader, also known as crawler skid or multi-purpose engineering vehicle, is a crawler-type special chassis equipment that uses the difference in the linear speed of the crawler tracks on both sides to achieve vehicle steering. It is mainly used in places where the work site is small, the ground is uneven, and the work content changes frequently. The supporting rollers are the main supporting components used to support the weight of the whole machine. They are arranged in two rows and are located on both sides of the crawler skid loader. A guide wheel is set at each end of each row of supporting rollers, forming a ring-shaped transmission wheel group with the driving wheel above them, plus two ring crawlers around the outside to form a set of crawler travel mechanism. Under the driving action of the travel motor, the crawler travel mechanism rotates to drive the whole machine to travel. The crawler travel mechanism replaces the wheel transmission mechanism of the wheeled skid loader. Compared with the wheeled skid loader, the crawler skid loader has greater traction and can adapt to worse working conditions. The supporting rollers play the role of transferring the weight of the whole machine to the crawler in the crawler travel mechanism. During the travel of the whole machine, the supporting rollers roll along the track surface and clamp the crawler to prevent it from derailing.

[0003] The existing supporting roller installation structure uses the method of installing the supporting rollers into the gantry beams on both sides of the frame from the bottom up through the fixing bolts on the left and right sides. The installation process of this structure requires external force to lift the bottom of the supporting roller and install the fixing bolts on both ends at the same time. The whole process requires two people to work together in a confined space at the same time. One person is constantly in a state of lifting heavy objects, which is easy to get tired; one person needs to complete the bolt pre-taping and tightening operations in a limited space, and the bolt pre-taping process requires two people to cooperate in the hole alignment operation, which has high requirements for personnel and low efficiency.

[0021] Example

[0022] like Figure 1-4 As shown, a track-type skid loader supporting wheel lifting and installation mechanism is mainly composed of a belt wheel chassis 1, a tray 2 and a jack 3. The belt wheel chassis 1, the jack 3 and the tray 2 are combined to complete the lifting of the supporting wheel and enable the supporting wheel to be adjusted in multiple dimensions within the set size, thereby avoiding the operation process of operators lifting heavy objects for a long time, greatly improving the safety of the operating environment of the operators, reducing the work intensity of the operators, and avoiding the waste of manpower caused by the cooperation of two people.

[0023] Among them, the pulley chassis 1 and the tray 2 are both rectangular structures welded by two specifications of 30×30 square steel. Round steels 11 are respectively provided at the four corners of the top of the pulley chassis 1, and connecting seats 12 are respectively provided at the four corners of the bottom of the pulley chassis 1, and pulleys 6 are installed in the connecting seats 12; through holes matching the round steel 11 are opened at the four corners of the tray 2, and the tray 2 is mounted on the round steel 11 through the four through holes, and a sleeve 4 is provided on the round steel 11 located between the pulley chassis 1 and the tray 2, and the top of the sleeve 4 is welded and fixed to the tray 2, and the two cooperate with each other to realize the upward and downward conductive movement.

[0024] A jack 3 is provided between the pallet 2 and the pulley chassis 1, and the jack 3 is connected to the pulley chassis 1 and the pallet 2 through a connecting structure 5, and the connecting structure 5 consists of a lower fixing seat 51 and an upper fixing seat 52, wherein the upper fixing seat 52 and the lower fixing seat 51 are respectively installed on the pallet 2 and the pulley chassis 1 in the middle of the length direction, the upper end face of the jack 3 is connected to the upper fixing seat 52, and the lower end face of the jack 3 is connected to the lower fixing seat 51, and the lower fixing seat 51 includes three square steels arranged in parallel, and the upper fixing seat 52 divides the pallet 2 into two rectangles of equal size along the length direction, each of which can hold a supporting wheel. The outer frame size of the pallet 2 is converted through the outer size of the supporting wheel and the size of the installation position, ensuring that the supporting wheel can be placed on the pallet 2 without causing interference. When in use, the force produced by the jack 3 is transmitted to the pallet 2 through the upper fixing seat 52.

[0025] At the same time, two pairs of arc-shaped concave surfaces 21 matching with the round surfaces of the end of the supporting rollers are provided on both sides of the top of the tray 2 along the length direction, and are arranged on both sides of the upper fixing seat 52 to prevent the supporting rollers from shifting left and right.

[0026] Working principle: while the jack 3 is lifted up and down under the action of the external rotational force, it drives the tray 2 to move up and down along the round steel 11 through the sleeve 4, and at the same time drives the supporting wheels on the tray 2 to move up and down; at the same time, the wheeled chassis 1 can allow the utility model to move forward, backward, left and right as a whole, and finally realize that the supporting wheel installation mechanism lifts the supporting wheel to move in multiple dimensions until it reaches the specified position and maintains a static and stable state, thereby providing the supporting wheel to be lifted and positioned from bottom to top and to achieve installation conditions for tightening on both sides.
