Description
Technical field
The present invention relates to coal mine equipment field, is a kind of hydraulic crane for middle trough specifically.
Background technology
In the mining process in colliery, a large amount of intermediate channel is needed to be used for coal to transfer out.And the installation of intermediate channel needs specialized equipment to realize, Chinese Patent Application No. 2009100112701, application people is Liaoning Xinfeng Coal Mine Electrical Equipment Manufacturing Co., Ltd., name is called that " lifting tool car of fully-mechanized equipment " discloses a kind of intermediate channel hydraulic hoisting equipment, its content is: lifting tool car of fully-mechanized equipment, rail wheel is had below vehicle frame, before, rear two ends are connected with stepping running gear, telescopic column is had above vehicle frame, telescoping crossbeam is connected with between telescopic column, on crossbeam, flexible deck post is connected with above hydraulically extensible column, the front of telescopic column is connected with telescopic arm crane, the chain of hoisting crane is connected with intermediate channel clamper, intermediate channel clamper has I-shape framework, the both sides of I-shape framework one end have hook two stay hooks outwardly respectively, there are hook two hinged hooks outwardly the both sides of the other end of I-shape framework, hinged hook hydraulic actuating cylinder is hinged with between the upper end of hinged hook and I-shape framework.The present invention is in the scraping transporter of fully-mechanized mining equipment is installed, intermediate channel and head, tail equipment can be installed, erection work labour intensity is little, installation rate is fast, work efficiency is high, erection work safety is good, there is stepping running gear, conveniently moving, be connected with flexible deck post above hydraulically extensible column, be conducive to work safety.In use, there is following shortcoming in this equipment: 1. because front and back transport plane and intermediate channel weight are comparatively large, and limits by underworkings width, the limited width of transport plane, go the shakiness that can cause transport plane in lifting process; 2., because transport plane size is comparatively large, can not transport by complete machine, parts need be resolved into and assemble in down-hole, waste time and energy, inefficiency; In addition, this equipment cannot allow the flat truck transporting intermediate channel to pass through, and after making to ship intermediate channel, flat truck must be pulled away by traction machine by flat truck at once at every turn, and then carrys out next car intermediate channel with flat truck transport, and efficiency is lower.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of folding, hydraulic hoisting car with bracing or strutting arrangement, concrete technical scheme is as follows:
A kind of hydraulic crane for middle trough, comprises vehicle frame, arm, boom luff oil cylinder, arm rotary oil cylinder etc., it is characterized in that: arrange bracing or strutting arrangement in the both sides of vehicle frame; Arrange retractor device between the vehicle frame of both sides, described retractor device comprises the vehicle frame telescopic oil cylinder being arranged on bottom of frame and the telescopic girder being arranged on vehicle frame top; Described two vehicle frame telescopic oil cylinders are coupling; Pinned connection is passed through between vehicle frame telescopic oil cylinder and vehicle frame.
For realizing stretching between two vehicle frames, described vehicle frame retractor device comprises two vehicle frame telescopic oil cylinders, and piston rod and the bottom of frame of described vehicle frame telescopic oil cylinder are coupling, and described two vehicle frame telescopic oil cylinders are coupling.
Described bracing or strutting arrangement comprises support arm, and described support arm is coupling with the piston rod of the support arm telescopic oil cylinder be arranged in vehicle frame, and under the driving of support arm telescopic oil cylinder, support arm is rotatable.
For ease of dismounting, ensure passing through of mine platform lorry, between described vehicle frame telescopic oil cylinder and vehicle frame, pass through pinned connection.
Described telescopic girder inside arranges hydraulic ram, is used for driving the flexible of telescopic girder.
Also comprise stepping crawling device, described stepping crawling device comprises the hydraulic enclasp device that before and after the wheel of bottom of frame, the oil cylinder of creeping being arranged on bottom of frame level, vehicle frame, bottom is arranged.
Advantage of the present invention is: arrange retractor device owing to adopting between vehicle frame, hydraulic crane for middle trough lateral dimension of the present invention is reduced greatly, can transport easily, remove dismounting operation from, substantially increase production efficiency between underground, owing to adding supporting construction, the reinforcement between frame downward both sides being deleted, not only ensure that the stability of hoisting machine, returns flat truck by having reserved space when lifting by crane intermediate channel, owing to passing through pinned connection between vehicle frame telescopic oil cylinder and vehicle frame, when hoisting machine work of the present invention, easily vehicle frame telescopic oil cylinder can be removed, thus ensure that the mine platform lorry of transport intermediate channel in columnly passes from hoisting machine, after the flat truck of every portion's transport intermediate channel is all passed by hoisting machine bottom, tow out together after lining up long line to the other side of hoisting machine, avoid transport a car intermediate channel then at once tow out mine platform lorry (if not being like this, the length of boom of hoisting machine cannot ensure operation distance), thus greatly save work capacity, raise the efficiency several times.In addition, adopt the technical scheme that described two vehicle frame telescopic oil cylinders are coupling, easy accessibility can be ensured on the one hand, the more important thing is: because this structure can ensure when needs frame width stretches, as long as give some power a little at described two vehicle frame telescopic oil cylinder places of being coupling, just can overcome " dead point " problem, facilitate the width adjustment of vehicle frame.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
Detailed description of the invention
Illustrate the present invention below in conjunction with accompanying drawing, as shown in Figure 1-Figure 3, the present invention includes vehicle frame 3, arm 1, boom luff oil cylinder 4, arm rotary oil cylinder 6 etc., bracing or strutting arrangement 2 is set in the both sides of vehicle frame 3; Arrange retractor device between the vehicle frame 3 of both sides, described retractor device comprises the vehicle frame telescopic oil cylinder 5 being arranged on bottom of frame and the telescopic girder 7 being arranged on vehicle frame top.
Described vehicle frame retractor device comprises two vehicle frame telescopic oil cylinders 5, is coupling bottom the piston rod of described vehicle frame telescopic oil cylinder 5 and vehicle frame 2, and described two vehicle frame telescopic oil cylinders 5 are coupling.
Described bracing or strutting arrangement 2 comprises support arm 21, and described support arm 21 is coupling with the piston rod of the support arm telescopic oil cylinder 22 be arranged in vehicle frame, and under the driving of support arm telescopic oil cylinder 22, support arm 21 can rotate around axle 23.
