Abstract
A large track crane arm frame flexible buffer device belongs to large track crane arm frame flexible buffer device, consisting of a stent and four cables. One end of the stent connects with a tower type vice jib, and the stent is arranged at binding part of the tower type vice jib and a main arm. Two kinds of the cables connect with the other end of the stent, one of the stent connects with the main arm, and the other cable connects with the tower type vice arm. The buffer device has the advantages that the performance is reliable, the installation is simple, the transportation is convenient, and the extension is easy, so the production cost is reduced, the enormous impact which is caused by the whole machine itself because of the backward inclination of the arm frame is solved, the former rigid buffer is changed into flexible buffer, the device is suitable for the combination mode of a plurality of arm frames such as main arm added with fixed vice arm and main arm added with tower type vice arm, and the stability and the safety in the working process of the crane is improved.
Description
Technical field
The utility model relates to a kind of shock absorber of crane arm support, particularly a kind of large-scale crawler crane boom flexible buffer device.
Background technology
At present, the crawler crane especially jib of large-tonnage crawler crane adopts the truss-like jib mostly, under the situation of fixing array mode such as auxiliary and tower auxiliary, thereby can exist the arm operation to produce the phenomenon of layback because of the elevation angle is excessive, cause danger to operation process, directly have influence on the stability of complete machine stability and jib self, therefore, the general jib shock absorber that adopts is improved on crawler crane.
Traditional jib shock absorber is to be connected with strut between the upper end of principal arm and auxiliary, and strut is a double-decker, between internal layer strut and outer strut spring is arranged, and is being rigidly connected of Jackstay type, utilizes spring that resistance is provided.Because being the increase with the product tonnage, the weight of devices such as the weight of jib self and drag-line, arm-tie improves, so when jib produces layback, impact to jib and car load is all very big, and the destruction of causing self structure easily can not guarantee the safety of working process.
Summary of the invention
The purpose of this utility model is that a kind of large-scale crawler crane boom flexible buffer device that can stop the jib layback, can guarantee the working process safety will be provided.
The purpose of this utility model is achieved in that this shock absorber has a support and four drag-lines, one end of support is connected on the tower auxiliary, be positioned at the binding site of tower auxiliary and principal arm, two drag-lines all are connected the other end of support, wherein two drag-lines are connected with principal arm, and two drag-lines are connected with tower auxiliary in addition.
Beneficial effect: owing to adopt such scheme, adopt flexible cable that tower auxiliary is connected with principal arm, the pulling force of dependence drag-line prevents the layback of tower auxiliary, support is installed on the tower auxiliary, with the other end of drag-line from support principal arm is connected with tower auxiliary respectively, the pulling force that provides by drag-line when jib has the trend of hypsokinesis stops this trend, thereby has guaranteed the safety of working process, effectively stop the layback of jib, reached the purpose of this utility model.This shock absorber dependable performance, simple installation, be convenient to transportation, be easy to advantage such as popularization, reduced production cost, solved the enormous impact that complete machine causes self because of the jib layback fully, the rigidity buffering that changes in the past is flexible buffer, be applicable to that principal arm adds the array mode that fixedly auxiliary and principal arm add multiple jibs such as tower auxiliary, has improved hoisting crane stability and safety in the course of the work.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
The specific embodiment
Embodiment 1: this shock absorber has a support 3 and two drag-lines 4 and two drag-lines 5, one end of support 3 is connected on the tower auxiliary 2, be positioned at the binding site of tower auxiliary 2 and principal arm 1, two kinds of drag-lines all are connected the other end of support 3, wherein a kind of drag-line 4 is connected with principal arm 1, and another kind of drag-line 5 is connected with tower auxiliary 2.
Choose satisfactory copper rope model, and make drag-line 4 and drag-line 5, use heat to prick the seamless tube welding support, lack otic placode in principal arm relevant position welding two, be used for connecting drag-line 4, be used for mounting bracket 3 at the bottom of tower auxiliary two otic placodes of welding, be used for installing drag-line 5 at two otic placodes of the another location of tower auxiliary welding, the otic placode that two directions are arranged in the end of support, the otic placode of a direction connects drag-line 4, the otic placode of a direction connects otic placode 5, and with principal arm 1 and tower auxiliary 2 usefulness drag-lines 4, drag-line 5 couples together by support 3 then.When tower auxiliary is swung back, provide pulling force to prevent layback by drag-line.
Claims (1)
