Description
Technical field
The utility model relates to the up-down bulk cargo that is used for the loading or unloading purpose or the device technique field of parcel.
Background technology
Along with Coal Mechanical melts the upgrading of adopting, domestic large and medium-sized colliery successively adopts hydraulic support to come top support plate, has greatly improved the percent recovery of safety and equipment; Reduce the downhole production personnel limitedly, but will be transported to new driving surface to hydraulic support, existed very big difficulty; Hydraulic support is light tens tons, heavy tens tons owing to there is not transportation means; Have to split into several parts to hydraulic support; New driving surfaces beyond piecemeal is transported to several kilometers by original tools such as winch, steel rope, the ropes made of hemp by manual work then get on,, reinstall use; And be difficult to reach precision and the performance that former factory installs between the hydraulic pressure of reinstalling, and take a lot of work, time-consuming, effort.Developed country has just produced and has used hydraulic support truck as far back as the eighties of last century 60-70 age; But according to the external hydraulic support truck service condition of domestic some large-scale mining industry institutional purchase, the hydraulic support truck of import can not satisfy that domestic coal mine well port is narrow, the ramp is little, the gradient is big and present situation such as state of ground difference; In order to solve above problem; The domestic hydraulic support truck that had occurred some according to the actual conditions development in domestic colliery at present; The situation that can effectively adapt to present domestic colliery, but existing hydraulic support truck front vehicle frame assembly and back have only simple vertical axis hinged between the frame assembly, four-wheel can not effectively be grabbed ground simultaneously during rugged road surface in running into the tunnel; The waste propulsive effort; And, make front vehicle frame assembly and back frame assembly receive torsion, reduction of service life because the hinge point of front vehicle frame assembly and back frame assembly adopts a vertical jointed shaft hinged.
The utility model content
The technical matters that the utility model will solve provides a kind of hydraulic support truck; Can realize when rugged road traveling that four-wheel effectively grabs simultaneously ground; Effectively utilize the power of engine installation output; Energy savings can also prevent effectively that front vehicle frame assembly and back frame assembly from receiving the infringement of relative torsion, increases the service life.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: the two-way linkwork of a kind of hydraulic support truck comprises vertical bearing pin, connection bearing assembly, the hinged ear of front vehicle frame, the back hinged ear of vehicle frame and connecting panel; The hinged ear of said front vehicle frame is hinged by means of vertical bearing pin with the hinged ear of back vehicle frame; Said back hinged ear of vehicle frame and the hinged ear of front vehicle frame include the hinged ear of monomer that two cover vertical equities are arranged; The hinged ear of front vehicle frame is hinged through two vertical bearing pins respectively with the hinged ear of back vehicle frame; The hinged ear of said back vehicle frame is captiveed joint with back frame assembly front end, and the hinged ear of said front vehicle frame is fixed at the connecting panel side of vertical setting; Said connection bearing assembly vertically is located at front vehicle frame assembly tail end; Said connecting panel is captiveed joint with said connection bearing assembly inner ring.
Said connection bearing assembly comprises two cover bearing and rotating shafts; Inner ring and said rotating shaft interference fit are all captiveed joint in the identical and outer ring of said two cover bearing arrangements with the front vehicle frame assembly; Said connecting panel is fixed at said rotating shaft tail end.
The beneficial effect of the utility model is following: the front vehicle frame assembly is connected with the connection bearing assembly by means of vertical bearing pin between the frame assembly with the back; Can realize the relative swing of front vehicle frame assembly and back frame assembly in the vertical direction; Effectively adapt to rugged road surface in the tunnel, prevent that single-wheel is unsettled, prevent that front vehicle frame assembly and back frame assembly receive the harm of torsion; Practice thrift power, increase the service life.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the front view of the utility model;
Fig. 2 is the birds-eye view of the utility model;
In the accompanying drawings: 1, back frame assembly; 2, the hinged ear of back vehicle frame; 3, vertical bearing pin; 4, the hinged ear of front vehicle frame; 5, connecting panel; 6, back frame assembly.
The specific embodiment
In sum, the utility model discloses the two-way linkwork of a kind of hydraulic support truck, comprise the hinged ear of vertical bearing pin 3, connection bearing assembly, front vehicle frame 4, the back hinged ear 2 of vehicle frame and connecting panel 5; The hinged ear 4 of said front vehicle frame and back vehicle frame hinged ear 2 are hinged by means of vertical bearing pin 3; Vehicle frame hinged ear 2 in said back includes the hinged ear of monomer that two cover vertical equities are arranged with the hinged ear 4 of front vehicle frame; The hinged ear 4 of front vehicle frame and back vehicle frame hinged ear 2 are hinged through two vertical bearing pins 3 respectively; The hinged ear 2 of said back vehicle frame is captiveed joint with back frame assembly 1 front end, and the hinged ear 4 of said front vehicle frame is fixed at connecting panel 5 sides of vertical setting; Said connection bearing assembly vertically is located at front vehicle frame assembly 6 tail ends; Said connecting panel 5 is captiveed joint with said connection bearing assembly inner ring.
Said connection bearing assembly comprises two cover bearing and rotating shafts; Inner ring and said rotating shaft interference fit are all captiveed joint in the identical and outer ring of said two cover bearing arrangements with front vehicle frame assembly 6; Said connecting panel 5 is fixed at said rotating shaft tail end.Adopt after the structure of the utility model the front vehicle frame assembly and afterwards be connected with the connection bearing assembly by means of vertical bearing pin between the frame assembly; Can realize the relative swing of front vehicle frame assembly and back frame assembly in the vertical direction; Effectively adapt to rugged road surface in the tunnel, prevent that single-wheel is unsettled, prevent that front vehicle frame assembly and back frame assembly receive the harm of torsion; Practice thrift power, increase the service life.
The two-way linkwork of the hydraulic support truck that the utility model disclosed can directly apply to 4 wheel driven hydrodynamic pressure bracket carrier; The 4 wheel driven bracket carrier is a kind of equipment that transports hydraulic support in the down-hole; Can also transport other underground equipment integral body to the down-hole,, make the major part of these equipment exempt from assembling in the down-hole like head, loader head and the crusher etc. of conveyer; Use manpower and material resources sparingly, improve installation effectiveness between the underground hydraulic pressure.
