Background technology
In the mining process in colliery, need a large amount of intermediate channel 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 " lifting tool car of fully-mechanized equipment " and discloses a kind of intermediate channel hydraulic hoisting equipment, its content is: lifting tool car of fully-mechanized equipment, there is rail wheel vehicle frame below, before, rear two ends are connected with stepping running gear, there is telescopic column vehicle frame top, between telescopic column, be connected with flexible crossbeam, on crossbeam, hydraulically extensible column top is connected with flexible deck post, 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, there are respectively hook two stay hooks outwardly the both sides of I-shape framework one end, there are hook two hinged hooks outwardly the both sides of the other end of I-shape framework, between the upper end of hinged hook and I-shape framework, be hinged with hinged hook hydraulic actuating cylinder.The utility model 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, hydraulically extensible column top is connected with flexible deck post, is conducive to work safety.In use, there is following shortcoming in this equipment: 1. due to front and back transport plane and intermediate channel weight larger, and limited by underworkings width, the width of transport plane is limited, goes can cause in lifting process the shakiness of transport plane; 2. because transport plane size is larger, can not transport by complete machine, need resolve into parts and assemble in down-hole, waste time and energy, inefficiency; In addition, this equipment cannot allow the flat truck that transports intermediate channel to pass through, and makes to ship after intermediate channel at every turn, and flat truck must be pulled away flat truck by traction machine at once, and then transports next car intermediate channel with flat truck, and efficiency is lower.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of folding, hydraulic hoisting car with bracing or strutting arrangement, and concrete technical scheme is as follows:
A kind of intermediate channel hydraulic hoisting car, comprises vehicle frame, arm, arm hoist cylinder, arm rotary oil cylinder etc., it is characterized in that: bracing or strutting arrangement is set in the both sides of vehicle frame; Between the vehicle frame of both sides, retractor device is set, described retractor device comprises the vehicle frame telescopic oil cylinder that is arranged on bottom of frame and the telescopic girder that is arranged on vehicle frame top.
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 that is arranged on the support arm telescopic oil cylinder in vehicle frame, and under the driving of support arm telescopic oil cylinder, support arm is rotatable.
For ease of dismounting, guarantee the passing through of mine platform lorry, between described vehicle frame telescopic oil cylinder and vehicle frame, by bearing pin, be connected.
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 the wheel of bottom of frame, the oil cylinder of creeping that is arranged on bottom of frame level, bottom, vehicle frame front and back arrange.
The utility model has the advantages that: owing to adopting between vehicle frame, retractor device is set, intermediate channel hydraulic hoisting car lateral dimension of the present utility model is reduced greatly, can between aboveground down-hole, transport easily, remove dismounting operation from, greatly improved production efficiency, owing to having increased supporting construction, the reinforcement between both sides, vehicle frame bottom is deleted, not only guaranteed that the stability of hoisting machine, returns flat truck by having reserved space when lifting intermediate channel, due between vehicle frame telescopic oil cylinder and vehicle frame, by bearing pin, be connected, when hoisting machine work of the present utility model, can easily vehicle frame telescopic oil cylinder be removed, thereby the mine platform lorry that guarantees transportation intermediate channel is in column, from hoisting machine, pass, after the flat truck of every transportation intermediate channel is all passed by hoisting machine bottom, to an other side of hoisting machine, line up after long line tow out together, avoided transporting 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 guarantee operation distance), thereby greatly saved work capacity, raise the efficiency several times.In addition, adopt described two technical schemes that vehicle frame telescopic oil cylinder is coupling, can guarantee easy accessibility on the one hand, the more important thing is: because this structure can guarantee when needs frame width is flexible, as long as give a little some power 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.
