Abstract
The utility model relates to a limiting and supporting device which comprises limiting oil cylinders, limiting movable blocks, limiting springs, spring supporting seats, a supporting oil cylinder, limiting movable slots, electromagnetic valves, hydraulic loops, a pressure sensor and fixed brackets. The limiting and supporting deice is characterized in that the supporting oil cylinder is arranged on a central position of the fixed brackets, and both sides at the upper end of the supporting oil cylinder are respectively provided with the spring supporting seat; the front ends of the spring supporting seats are provided with the limiting springs; the front ends of the limiting springs are provided with the limiting movable blocks, and the limiting movable blocks are directly connected with the limiting oil cylinders; the upper ends of the fixed brackets are provided with the limiting movable slots, and the limiting movable blocks are arranged in the limiting movable slots; the limiting oil cylinders are connected with the supporting oil cylinder; and the electromagnetic valves and the pressure sensor are arranged on the hydraulic loops. The limiting and supporting device has the advantages that the defect of incapacity of precise jointing of the traditional machines is overcome, and the arm frame can be precisely positioned and fixed, so that equipment is effectively protected, and artificial damages cannot be caused.
Description
Technical field
The utility model belongs to field of mechanical technique, a kind of spacing support device of saying so more specifically.
Background technique
At present, a lot of engineering mechanical devices all have long operation jib, for example concrete mixer, hoist etc., and jib is the core component of these equipment; Often big, the Heavy Weight of volume generally adopts hydraulic driving in the time of in the jib operation, because hydraulic power is powerful, protects not in place or operate miss a little; Will cause the destruction of equipment itself, therefore, the protection of jib had relatively high expectations; The jib supporting way of existing technology be simple machinery mount mostly, because machinery mount can not adjusted position, and jib up and down can both activity about being; Whether and the position can not accurately adjust, under the fixing situation of jib placement location, can only rely on operator's subjective judgement suitable; Higher in the operating process to the operator dependency degree, be unfavorable for the protection of jib, also usually bring artificial damage to equipment.
Summary of the invention
In order to address the above problem, the utility model provides a kind of spacing support device, and jib supporting part and stop portion are separated; And through hydraulic pipe line the two is connected, because load-bearing member contact jib earlier, the load-bearing oil cylinder will provide power to stop portion in the process of pressing down; When spacing completion, locating oil cylinder can not continue to absorb the pressure oil of support cylinder, and this moment, jib continued to move downward with the support cylinder internal pressure is raise; Pressure transducer sent the signal that puts in place when pressure was raised to setting value, and this signal can make jib forbid pressing action, simultaneously; Cut off the connection oil circuit between locating oil cylinder and the support cylinder, make support cylinder and locating oil cylinder independent fully, owing to locating oil cylinder and support cylinder have been broken off the oil circuit with extraneous UNICOM; Oil cylinder will keep stationary state, support and fixing function thereby reach.
Described spacing support device is made up of locating oil cylinder, spacing movable block, limit spring, spring support, support cylinder, spacing loose slot, solenoid valve, oil hydraulic circuit, pressure transducer, fixed support; It is characterized in that on the support bracket fastened central position support cylinder being set; The both sides, upper end of support cylinder are provided with spring support respectively; The front end of spring support is provided with limit spring, and the front end of limit spring is provided with spacing movable block, and spacing movable block directly is connected with locating oil cylinder; Support bracket fastened upper end is provided with spacing loose slot; Spacing movable block is arranged in the spacing loose slot, and locating oil cylinder is connected with support cylinder through oil hydraulic circuit, and solenoid valve and pressure transducer are set on the oil hydraulic circuit.
The beneficial effect of the utility model is: spacing support device has overcome traditional mechanical and has supported the shortcoming that can't accurately be connected, and can the accurate positioning and fixing of jib have been protected equipment effectively, can not cause artificial damage.
