Abstract
The utility model provides an insert-type connecting rod hydraulic support comprising a top beam which hinges to a rear beam, a base and a hydraulic column which is connected and supported between the top beam and the base, wherein an elevating connecting rod is disposed between the top beam and the base and hinges to the top beam through a pin, the bottom of the elevating connecting rod being inserted to a mantle cavity of the connecting rod case which is fastened to the base, the elevating connecting rod moving up and down and back and forth along the connecting rod case under the drive of the hydraulic column. The support herein overcomes the deficiencies of prior art technology, such as large space occupation, and inconvenient and safety issues in construction. The utility model has the advantages of tight structure, easy adjustment, convenient installation and dismounting, small space occupation, and easy arrangement of pedestrian space inside the support.
Description
Technical field
The utility model relates to a kind of safety support device that is used for mine working face; particularly a kind of being applicable to needs hydraulic support to cover the various work planes and the supporting plug-in type connecting rod hydraulic support of various kinds of equipment of supporting; realize arranging effective safe pedestrian space, the protection underground labour walks between support and the safety during operation.
Background technology
The work plane of modern fully-mechanized mining and all kinds of corollary equipment need that all hydraulic support is set and cover supporting.Especially top coal caving work plane, owing to use forward and backward two transporters, so in the apparatus arrangement of the coordinative composition of equipments of transporter and hydraulic support and coal-winning machine and work plane, often take up space bigger because of the head of forward and backward transporter, the motor reducer at tail place, but need hydraulic support that it is all covered supporting, so cause the transitional hydraulic bracket base portion narrow space at head or tail place, construction operation is very inconvenient.And the hydraulic support that traditional quadric chain is formed though it is strong to have resistance to torsion, is heightened advantages such as scope is big, but needs to take bigger space.In above-mentioned space, need to arrange in the transition bracket operation of forward and backward transporter and driving section thereof, often because quadric chain has occupied most interior space, and cause the workman when support is released anterior transporter, to walk in the slave road, perhaps cross from drive of motor portion top, this operating environment can cause serious accident, has the hidden danger of harm construction operation safety.
The utility model content
The purpose of this utility model provides a kind of plug-in type connecting rod hydraulic support, it has overcome taking up room greatly that prior art exists, construction operation is very inconvenient, the defective that has harm construction operation potential safety hazard, its compact conformation is easily adjusted, and is easy to loading and unloading, space hold is little, is easy to arrange in frame safe pedestrian space.
The technical scheme that the utility model adopted is: this plug-in type connecting rod hydraulic support comprise back timber, base and the connection that is hinged with tail boom and be supported on back timber and base between hydraulic vertical prop, its technical essential is: be provided with between described back timber and base with bearing pin and the hinged lifting linking member of described back timber, and the bottom that makes described lifting linking member is inserted in the connecting rod housing-case chamber that is fixed together with described base, under the drive of hydraulic vertical prop, described lifting linking member is along upper and lower the moving back and forth in described connecting rod housing-case chamber.
The axis direction of the bearing pin that described lifting linking member and described back timber are hinged and the axis direction of described lifting linking member are perpendicular.
Advantage and the good effect that the utlity model has are: owing to be provided with between the back timber of this plug-in type connecting rod hydraulic support and the base with bearing pin and the hinged lifting linking member of back timber, so lifting linking member is easy for installation, back timber is followed the top board angle and is easily adjusted during use; Lifting linking member is upper and lower reciprocating motion under the drive at hydraulic vertical prop in connecting rod housing-case chamber, realizes the adjustment of support height easily; Lifting linking member is plugged in the connecting rod housing-case and moves back and forth simultaneously, and space hold is little, the convenient safe pedestrian space of arranging in support.
If the axis direction of the bearing pin that lifting linking member and back timber are hinged keeps vertical mutually with the axis direction of lifting linking member, so just can in the adjustment of realization support height, limit the rotation of back timber effectively with respect to base, resistance to torsion is strong.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure schematic diagram of the present utility model.
Sequence number explanation among the figure: transporter, 9 back transporters before 1 back timber, 2 bases, 3 hydraulic vertical props, 4 lifting linking members, 5 tail booms, 6 tail boom hydraulic cylinders, the 7 connecting rod housing-cases, 8.
The specific embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1.This plug-in type connecting rod hydraulic support comprises the back timber 1 that is hinged with tail boom 5, base 2 and connects and be supported on parts such as hydraulic vertical prop 3 between back timber 1 and the base 2 and lifting linking member 4.The tail boom 5 that wherein is hinged on back timber 1 rear portion connects by tail boom hydraulic cylinder 6 and is supported on the base 2, utilizes tail boom hydraulic cylinder 6 to adjust the anglec of rotation and the supporting position of tail booms 5.Lifting linking member 4 is arranged between back timber 1 and the base 2, hinged with bearing pin and back timber 1, and the bottom that makes lifting linking member 4 is inserted in connecting rod housing-case 7 chambeies that are fixed together with base 2, under the drive of hydraulic vertical prop 3, lifting linking member 4 is finished the Height Adjustment of support along upper and lower the moving back and forth in connecting rod housing-case 7 chambeies.
Do not rotate in lifting process in order to ensure back timber 1, should make the axis direction of the axis direction of the hinged bearing pin of lifting linking member 4 and back timber 1 and lifting linking member 4 perpendicular, to strengthen its resistance to torsion with respect to base.
During use, the installation of plug-in type connecting rod hydraulic support is identical with the regulation of existing support with the Job Operations method.As long as each parts is transported in the tunnel that needs supporting, lifting linking member 4 tops are with after back timber 1 usefulness bearing pin is connected, and the bottom of lifting linking member 4 is plugged in connecting rod housing-case 7 chambeies, and all the other each parts install according to illustrated traditional location and get final product.
During operation, rise hydraulic vertical prop 3, back timber 1 supports roof, install and arrange corollary equipment such as forward and backward transporter 8,9 after, working face equipment is arranged ready.The workman can stand in the space between hydraulic vertical prop shown in Figure 13 and the lifting linking member 4, handles support, passes and draws and move front and rear portions transporter 8,9 and carry out coal mining activity, and handle ascending, descending and walking that support hydraulic system is finished support.
