Abstract
The utility model relates to a tensioning oil cylinder, which is characterized by comprising a cylinder body (1). The top of the cylinder body is provided with an oil injection valve (8), a piston (7) is positioned in the cylinder body (1), and a piston rod of the piston (7) is connected with the bottom of the oil injection valve (8). A spring seat (2) is arranged on the periphery of the lower portion of the cylinder body (1), a spring (4) is installed on the spring seat (2), the top of the spring is provided with a spring cover (3), the spring (4) is fixed by the spring seat (2) and the spring cover (3), and the top of the spring cover (3) is provided with a nut (5) which is fixed on the cylinder body (1) through a screw (6). With the spring arranged outside the cylinder body, the tensioning oil cylinder enables a crawler belt to have certain pre-tension force. Being confronted with impact, the spring continuously stretches out and draws back to perform buffering. The tensioning oil cylinder is simple in structure, safe, reliable and convenient to modify.
Description
Technical field
The utility model relates to a kind of tensioning hydro-cylinder, is mainly used in the traveller of crawler excavator.
Background technique
Crawler excavator has advantages such as tractive force is big, grade ability is strong, and radius of turn is little, has therefore obtained using widely in engineering construction and mine development.Tension device has played important role in the crawler excavator, common crawler excavator adopts tensioning screw to be used as its tension device, yet the rigidity of screw rod is better, not yielding, when crawler belt is subjected to impacting, crawler belt can not be in tensioning state at any time, and the effect of its tensioning will be had a strong impact on.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can keep the pre-tensioning of crawler belt, and can absorb vibration, prevents the tensioning hydro-cylinder that crawler belt damages.
The purpose of this utility model is achieved in that
The utility model tensioning hydro-cylinder, comprise cylinder body, its top is provided with fuel feeding valve, and the inside of cylinder body is provided with piston, and the piston rod of described piston links to each other with the bottom of fuel feeding valve, the periphery of described inferior part of the cylinder block is provided with spring seat, described spring seat is provided with spring, and the top of described spring is provided with spring cup, and described spring seat and spring cup are fixed spring, the top of described spring cup is provided with nut, described nut by screw on cylinder body.
Compared with prior art, the beneficial effects of the utility model are:
This tensioning hydro-cylinder makes crawler belt have certain pre-tensioning by the outer spring of cylinder body, when running into impact in the walking process of crawler belt, spring can constantly stretch and play buffer function, and this tensioning hydro-cylinder is simple in structure, and is safe and reliable, and repacking is convenient.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model tensioning hydro-cylinder.
Wherein: cylinder body 1, spring seat 2, spring cup 3, spring 4, nut 5, screw 6, piston 7, fuel feeding valve 8.
Embodiment
Referring to Fig. 1, the utility model relates to a kind of tensioning hydro-cylinder, comprise cylinder body 1, described cylinder body 1 is vertically placed, its top is provided with fuel feeding valve 8, the inside of cylinder body 1 is provided with piston 7, the piston rod of described piston 7 links to each other with the bottom of fuel feeding valve 8, the periphery of described cylinder body 1 bottom is provided with spring seat 2, and described spring seat 2 is provided with spring 4, and the top of described spring 4 is provided with spring cup 3, described spring seat 2 and spring cup 3 are fixing with spring 4, the top of described spring cup 3 is provided with nut 5, and described nut 5 is fixed on the cylinder body 1 by screw 6, and described nut 5 is used for spring cup 3 spacing.
This tensioning hydro-cylinder makes crawler belt have certain pre-tensioning by the spring 4 outside the cylinder body 1, when running into impact in the walking process of crawler belt, spring 4 can constantly stretch and play buffer function, and this tensioning hydro-cylinder is simple in structure, and is safe and reliable, and repacking is convenient.
