Description

Technical Field

[0001] This utility model relates to the field of roadway support equipment, specifically, to an integrated sliding advanced support device for transport roadways. Background Technology

[0002] Currently, in coal mines, support equipment and transportation equipment are deployed simultaneously in fully mechanized mining and longwall mining faces, but these various devices operate independently. For example, existing sliding advance support devices are generally used in tunneling roadways or alone in transportation roadways. They only support the roadway roof, have no connection with the transfer machine, do not provide power to the transfer machine, and occupy a large space.

[0003] Utility model patent CN219061724U discloses a sliding pre-support hydraulic support for canopy roadways, comprising a front frame and a rear frame. The front frame includes a first longitudinal beam, a first transverse beam, an inner frame left top beam, and an inner frame right top beam. The first transverse beam is connected to the first longitudinal beam. The inner frame left and right top beams are both connected to two first transverse beams. The lower parts of the inner frame left and right top beams are connected to vertical linear drive pairs. The rear frame includes a second longitudinal beam, a second transverse beam, an outer frame left top beam, and an outer frame right top beam. The second transverse beam is connected to the second longitudinal beam. The outer frame left and right top beams are both connected to two second transverse beams. The lower parts of the outer frame left and right top beams are connected to vertical linear drive pairs. A pushing jack is connected between the first and second transverse beams. The sliding-type advanced support hydraulic support used in this scaffolded roadway moves in a sliding manner, enabling the support to remain within the roof and providing greater support strength and rigidity. It also achieves mechanization and reduces the labor intensity of workers. However, the disclosed structure of this sliding-type advanced support hydraulic support for scaffolded roadways is not integrated with the transfer machine, thus failing to meet the requirements of equipment integration and reducing the space occupied by the equipment. Utility Model Content

[0004] In order to improve support efficiency, increase equipment integration, and reduce equipment space occupation, the technical solution adopted by this utility model is: an integrated sliding advance support device for transport roadways, including a transfer machine, at least two pairs of independently set support sub-frames, and at least two pairs of support main frames set on the transfer machine;

[0005] The auxiliary support frame and the main support frame are arranged at intervals along the length of the transfer machine, and a pushing jack is connected between the auxiliary support frame and the main support frame. The pushing jack is used to drive the auxiliary support frame, the main support frame and the transfer machine to move forward by extending and retracting itself.

[0006] Based on the above, in order to achieve alternating support, the support sub-frame includes a pair of sub-frame columns, the pair of sub-frame columns are arranged along the width direction of the transfer machine, the sub-frame columns are connected by sub-frame crossbeams, and several sub-frame longitudinal beams are provided between two adjacent sub-frame crossbeams.

[0007] The main support frame includes a pair of main frame columns, which are arranged along the width of the transfer machine. Main frame crossbeams are connected between the main frame columns, and several main frame longitudinal beams are provided between two adjacent main frame crossbeams.

[0008] The secondary frame longitudinal beams are arranged at intervals with the main frame longitudinal beams.

[0009] Based on the above, in order to facilitate stepping and moving, the pushing jack is connected to the top of the two adjacent main frame columns and the auxiliary frame columns.

[0010] Based on the above, at least two pairs of the aforementioned support subframes have the same specifications.

[0011] Based on the above, in order to increase the degree of freedom of the main support frame, a pair of guide sleeves are provided at one end of the transfer machine, one pair of the main support frames are located in the guide sleeves, and the other pair of the main support frames are connected to the transfer machine by a spherical hinge.

[0012] Based on the above, a sub-frame guide rubber block is provided between the lower part of the sub-frame column and the lower part of the transfer machine. The sub-frame guide rubber block is used to control the distance between the sub-frame column and the transfer machine.

[0013] Based on the above, several of the sub-frame longitudinal beams and the sub-frame transverse beams are hinged together by pins, and several of the main frame longitudinal beams and the main frame transverse beams are hinged together.

[0014] This utility model has substantial features and advancements compared to existing technologies. Specifically, the integrated sliding advance support device for transport roadways provided by this utility model adopts a support method consisting of a main support frame, main frame columns, secondary support frames, and secondary frame columns. The main frame columns of the main support frame are connected to the transfer machine, while the secondary support frame is designed separately. The main support frame and the secondary support frame move forward alternately in a stepping manner by extending and retracting the push jacks. This eliminates the need for a self-moving mechanism on the transfer machine. The forward movement is mainly achieved by the power of the push jacks and end supports between the main support frame and the secondary support frame, thereby simplifying the equipment structure, improving the integration of the equipment, increasing the stability of the equipment, and reducing the space occupied by the equipment.

[0015] Furthermore, by detachably installing a subframe guide rubber block at the position where the subframe base coincides with the transfer machine, the gap between the subframe base and the transfer machine can be controlled using the subframe guide rubber block to prevent the subframe from deviating.

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0021] Example 1

[0022] This embodiment provides an integrated sliding advance support device for transport roadways, such as... Figure 1 , Figure 2 , Figure 3 As shown, the system includes a transfer machine 7, two pairs of independently configured auxiliary support frames, and two pairs of main support frames mounted on the transfer machine 7. The auxiliary support frames and the main support frames are arranged at intervals along the length of the transfer machine 7, and a pushing jack 5 connects the auxiliary support frames and the main support frames. The pushing jack 5 is used to move the auxiliary support frames, the main support frames, and the transfer machine forward by extending and retracting itself.

[0023] Specifically, the support subframe includes a pair of subframe columns 1, which are arranged along the width direction of the transfer machine 7. Subframe crossbeams 2 are connected between the subframe columns 1, and several subframe longitudinal beams 10 are arranged between two adjacent subframe crossbeams 2.

[0024] The main support frame includes a pair of main frame columns, which are arranged along the width of the transfer machine 7. Main frame crossbeams 6 connect the main frame columns, and several main frame longitudinal beams 3 are arranged between adjacent main frame crossbeams 6; the auxiliary frame longitudinal beams 10 are arranged at intervals with the main frame longitudinal beams 3. For ease of distinction, based on their distribution, the main frame columns can be divided into a pair of front main frame columns 4 and a pair of rear main frame columns 9.

[0025] Example 2

[0026] This embodiment provides an integrated sliding advance support device for transport roadways. The main difference from Embodiment 1 is that, in this embodiment, to facilitate stepping and movement, the pushing jacks are connected to the tops of two adjacent main frame columns and auxiliary frame columns 1. The two pairs of auxiliary support frames are of the same specifications.

[0027] Example 3

[0028] This embodiment provides an integrated sliding advance support device for transport roadways. The main difference from Embodiment 1 is that, in this embodiment, in order to increase the degree of freedom of the main support frame, a pair of guide sleeves are provided at one end of the transfer machine. One pair of the main support frames is located in the guide sleeves, and the other pair of the main support frames is connected to the transfer machine by a spherical hinge.

[0029] Specifically, a pair of front main frame columns 4 are disposed within the guide sleeve. A pair of rear main frame columns 9 are connected to the transfer machine via spherical hinges.

[0030] Several of the sub-frame longitudinal beams 10 are hinged to the sub-frame crossbeams 2 via pins, and several of the main frame longitudinal beams 3 are hinged to the main frame crossbeams 6.

[0031] Example 4

[0032] This embodiment provides an integrated sliding advance support device for transport roadways. The main difference from Embodiment 1 is that, in this embodiment, a sub-frame guide rubber block 8 is provided between the lower part of the sub-frame column 1 and the lower part of the transfer machine 7. The sub-frame guide rubber block 8 is used to control the distance between the sub-frame column 1 and the transfer machine 7.

[0033] Specifically, the moving steps of the integrated sliding advance support device for transport roadways provided by this utility model are as follows:

[0034] During the stepping movement, the lifting states of the main support frame and the auxiliary support frame are different. That is, when the main support frame retracts, the auxiliary support frame's crossbeams and longitudinal beams support the support frame from above, thereby driving the transfer machine upward and lifting it off the ground. Then, by extending the push jacks, the transfer machine is moved forward.

[0035] After being moved into position, the main support frame extends to support the ground, then the secondary support frame retracts and lifts off the ground. Subsequently, the push jacks retract, moving the secondary support frame forward. Once in position, the secondary support frame extends to support the ground, thus completing the stepping movement.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
