The utility model discloses increased the whole braking torque of hoist, realized the braking requirement of large-tonnage heavy object hoist, the installation is maintained conveniently.
Description
Technical Field
The utility model relates to a dynamic compactor field, specific hoist arresting gear for crawler-type dynamic compactor that says so.
Background
At present, the mechanical winch of the crawler-type dynamic compaction machine produced in China is mostly braked by an external holding brake or a caliper disc brake. The external holding type brake is complex in maintenance and adjustment, poor in braking effect, convenient to maintain and free of adjustment, and a caliper disc type brake cannot meet the requirement of braking torque along with the lifting of weight.
Disclosure of Invention
For solving the technical problem that above-mentioned exists, the utility model provides a hoist arresting gear for crawler-type dynamic compactor has increased the whole braking torque of hoist, has realized the braking requirement of large-tonnage heavy object hoist, and the installation is maintained conveniently.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a hoist arresting gear for crawler-type dynamic compactor, includes jaw type stopper one, friction disc, hoist brake disc and jaw type stopper two, the hoist brake disc sets up in one side of hoist reel, jaw type stopper one and jaw type stopper two are fixed respectively and set up in the both sides of hoist brake disc symmetric position, the brake cylinder piston rod of jaw type stopper one, jaw type stopper two is fixed connection friction disc respectively, extrudes the braking that the friction disc realized the hoist brake disc on to the hoist brake disc through hydraulic control brake cylinder piston rod.
The first clamp brake and the second clamp brake are respectively arranged on the winch platform and the A-shaped frame seat lug.
The friction plate is of a structure formed by combining a metal plate and a wear-resistant material.
The utility model discloses simple structure fixes respectively in the both sides of hoist brake disc symmetric position and sets up the caliper brake, has satisfied the requirement of the braking torque of large-tonnage heavy object promotion in-process, and two brakers pass through the bolt and install on hoist engine platform or A type frame seat ear, and the installation and the maintenance of being convenient for, the friction disc adopts the design that sheetmetal and wear-resisting material combined, and life is longer, and braking effect is better, and the cost of manufacture is low, and the security performance is high, the extensive popularization and application of being convenient for.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention is described in detail below with reference to the following figures and specific embodiments:
as shown in fig. 1, a hoist brake device for crawler-type dynamic compactor includes first caliper brake 1, friction disc 2, hoist brake disc 3 and second caliper brake 4, hoist brake disc 3 sets up in one side of hoist reel, first caliper brake 1 and second caliper brake 4 are fixed respectively in the both sides of 3 symmetric positions of hoist brake disc, the brake cylinder piston rod of first caliper brake 1, second caliper brake 4 is fixed connection friction 2 respectively, extrudes friction disc 2 through hydraulic control brake cylinder piston rod to hoist brake disc 3 and realizes the braking of hoist brake disc 3.
Preferably, the first caliper brake 1 and the second caliper brake 4 are respectively arranged on the winch platform and the A-shaped frame seat lug.
Preferably, the friction plate 2 is formed by combining a metal plate and a wear-resistant material.
In this embodiment, the first caliper brake 1 and the second caliper brake 4 are respectively fixed to the winch platform and the a-type frame seat lug through bolts and located on two sides of the symmetrical position of the winch brake disc 3, and the friction plates 2 are respectively fixed to the first caliper brake 1 and the second caliper brake 4 through bolts and connected to a piston rod of the brake cylinder, so that the hydraulic braking stability is high. When the winch needs to be braked, the piston rod of the brake oil cylinder is controlled by the hydraulic device to extrude towards the direction of the winch brake disc 3 to realize braking, and the arrangement positions of the two caliper brakes realize that the optimal braking torque is applied to the winch brake disc 3, so that the most stable braking effect is realized. The utility model discloses easy dismounting, it is convenient to maintain, and the security performance is high, long service life, low in production cost is fit for extensive popularization and application.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
