Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of truss installation, and more particularly to a truss translation device and a truss installation method. BACKGROUND

[0002] A truss is a lattice structure formed by connecting multiple bar members through nodes, and its core principle is to realize load transmission and distribution through the geometric stability of triangular units. According to the structure form, it can be divided into planar trusses (such as simply supported trusses, continuous trusses, cantilever trusses) and spatial trusses (such as net truss structures), and according to the material classification, it includes steel trusses, aluminum alloy trusses, wood trusses, etc. Trusses are widely used in fields such as construction, bridges, coal mine construction, and mechanical manufacturing. Its characteristics are that the bar members mainly bear axial tension or pressure, the material utilization rate is high, and the self-weight is light. At the same time, it has the advantages of convenient construction and strong economy, and can adapt to the needs of large-span or complex stress scenarios.

[0003] In the operation of a coal mine, the existing trusses are mostly fixedly installed on the ground or supports, and their position and form are difficult to adjust after construction. When the truss needs to be translated, if disassembly and assembly operations are performed, not only a lot of time and manpower are required, but also sparks or structural damage to the support position may occur during the disassembly and assembly process, which may cause safety hazards. Therefore, a translatable truss system is urgently needed to realize flexible displacement of the truss in the horizontal direction, thereby improving the construction efficiency of the coal mine.

[0004] A patent with the Chinese invention patent publication number CN114059783A discloses a truss translation device and a truss installation method. The technical solution points of the patent are as follows: a truss main body and support frame bodies vertically connected at both ends of the truss main body are included. The support frame bodies include a support bottom beam, a first support column, a second support column, and a walking roller. The two ends of the support bottom beam are fixedly connected to the lower ends of the first support column and the second support column, respectively. The upper ends of the first support column and the second support column are connected in an inverted V shape. The walking roller is arranged at the bottom of the support bottom beam. One or more hoisting points are arranged on the lower side of the truss main body. An electric hoist is arranged on each hoisting point. The present application uses a steel truss translation device to sequentially assemble and translate each piece from the initial position of the truss main body to the installation position according to the sequence specified in the scheme. The present application can quickly assemble and translate the truss to the installation position in a site with a small lifting capacity and a narrow construction area, thereby reducing the difficulty of installing the truss structure in place.

[0005] But the above technology often has the following defects: the existing technology is pulled by the winch to pull the movable hook to make the support frame body walk on the guide rail of the building roof laying through the walking roller, because the track is often laid in a straight line or needs to be laid in a large radius corner, which is very flexible for the limited operation environment of the coal mine underground, so a more flexible translation device is needed to help the truss move in multiple directions.

DETAILED DESCRIPTION

[0031] The technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application, and in addition, the forms of each structure described in the following embodiments are only examples, and the truss translation device and the truss installation method involved in the present application are not limited to each structure described in the following embodiments, and all other embodiments obtained by the ordinary skilled person in the art without making creative efforts belong to the protection scope of the present application.

[0032] Reference Figures 1-5 The present application provides a truss translation device, which comprises a truss assembly, further comprises a longitudinal lifting assembly 2 fixedly connected at the bottom of the truss, a transverse lifting assembly 3 fixedly connected on the longitudinal lifting assembly 2, a platform vehicle assembly 4 fixedly connected on the transverse lifting assembly 3, and a support frame assembly 5 fixedly connected on the platform vehicle assembly 4.

[0033] The truss assembly 1 comprises a three-dimensional structure beam 11, a miner lamp 12 fixedly connected to the three-dimensional structure beam 11, a stand 13 fixedly connected to both sides of the three-dimensional structure beam 11, and a mounting seat 14 fixedly connected to the stand 13.

[0034] The longitudinal lifting assembly 2 comprises a longitudinal claw 21 fixedly connected to the mounting seat 14, a longitudinal sliding block 22 fixedly connected to the claw, a profiled lead screw 23 rotatably connected to the longitudinal sliding block 22, a longitudinal guide rail 24 slidably connected to the longitudinal sliding block 22, a longitudinal stepping motor 25 fixedly connected to the longitudinal guide rail 24, and a partition column 26 fixedly connected to the longitudinal guide rail 24.

[0035] The transverse lifting assembly 3 comprises a transverse guide rail 31 fixedly connected to the partition column 26, a transverse stepping motor 32 fixedly connected to the transverse guide rail 31, a long lead screw 33 fixedly connected to the transverse stepping motor 32, a transverse sliding block 34 rotatably connected to the long lead screw 33, and a transverse claw 35 fixedly connected to the transverse sliding block 34.

[0036] The profiled lead screw 23 is shorter than the long lead screw 33, and the horizontal height of the longitudinal sliding block 22 is the same as that of the transverse sliding block 34.

[0037] The profiled lead screw 23 is divided into two parts by the middle part, and the threads on the two sides are opposite in rotation direction, and the long lead screw 33 is the same.

[0038] Specifically, the three-dimensional structure beam 11 in the truss assembly 1 is a three-dimensional truss structure, which is used for mounting the miner lamp 12 and needs to bear the vertical load. The stand 13 and the mounting seat 14 are used for reinforcing and positioning the beam. Common trusses are usually fixed structures and cannot be moved after installation. The operation requirements of coal mines are complex and variable, and the fixed truss system cannot meet the requirements.

[0039] The longitudinal lifting assembly 2 and the transverse lifting assembly 3 grasp and fix the structural members of the mounting seat 14 through the longitudinal claw 21 and the transverse claw 35. The longitudinal sliding block 22 can move under the action of the longitudinal stepping motor 25 and the profiled lead screw 23. Since the threads on the two ends of the profiled lead screw 23 are opposite in rotation direction, when the stepping motor rotates, the two longitudinal sliding blocks 22 will move closer or farther away at the same time. The transverse stepping motor 32, the long lead screw 33, and the transverse sliding block 34 are the same. In this way, different mounting seats 14 can be compatible. The partition column 26 separates the longitudinal guide rail 24 and the transverse guide rail 31 to prevent interference.

[0040] Referring to Figures 6-7 The platform vehicle assembly 4 comprises an outer shell 41 fixedly connected to the transverse guide rail 31, a long groove 42 formed in the outer shell 41, a side plate 43 fixedly connected to the outer shell 41, and a Mecanum wheel 44 rotatably connected to the outer shell 41.

[0041] The support frame assembly 5 comprises a tension torque sleeve 51 fixedly connected to the side plate 43, a large arm 52 rotatably connected to the tension torque sleeve 51, a support rod 53 fixedly connected to the large arm 52, an end sleeve 54 rotatably connected to the end of the large arm 52, and a support plate 55 fixedly connected to the end sleeve 54.

[0042] The support frame assembly 5 comprises an inclined support sleeve 56 fixedly connected to the side plate 43, a hydraulic cylinder rotating block 57 rotatably connected to the inclined support sleeve 56, and an inclined support arm sleeve 58 slidably connected to the hydraulic cylinder rotating block 57, wherein the inclined support arm sleeve 58 is rotatably connected to the support rod 53.

[0043] Specifically, after the longitudinal lifting assembly 2 and the transverse lifting assembly 3 fix the mounting seat 14, the weight of the truss is transferred to the outer shell 41, which is made of thickened steel plates and has high strength. The long groove 42 is used for installing the transverse guide rail 31, and the side plate 43 is used for installing the support frame assembly 5. The platform vehicle assembly 4 adopts the Mecanum wheel 44. When the truss needs to be moved, the Mecanum wheel 44 can be controlled to rotate and rotate at a certain speed, so that the truss can move flexibly in front, back, left and right directions, facilitating the rapid layout and installation of the truss.

[0044] When the truss needs to be fixed, the Mecanum wheel 44 stops moving, and the hydraulic cylinder rotating block 57 provides hydraulic power to retract the inclined support arm sleeve 58. The inclined support arm sleeve 58, the large arm 52 and the side plate 43 form a crank linkage system, which presses down the large arm 52. Under the pressure of the large arm 52, the support plate 55 is tightly attached to the ground through the end sleeve 54, increasing the contact area with the ground and the load capacity and stability of the platform vehicle assembly 4. When the truss needs to be removed, the hydraulic cylinder rotating block 57 lifts the inclined support arm sleeve 58, and the large arm 52 and the support plate 55 are lifted. At this time, the Mecanum wheel 44 contacts the ground and starts to rotate, driving the truss to translate.

[0045] Referring to Figures 1-6 , a truss installation method of a truss translation device is provided:

[0046] S1: After assembling the truss assembly 1 on the ground, hoist the truss assembly 1 by a crane, control the transverse stepping motor 32 or the longitudinal stepping motor 25, align the transverse clamping jaw 35 or the longitudinal clamping jaw 21 with the mounting seat 14, and lower the truss assembly 1 to fix the mounting seat 14 on the transverse lifting assembly 3 and the longitudinal lifting assembly 2;

[0047] S2: control the support frame assembly 5 to move the large arm 52 and the support plate 55 upward, control the platform vehicle assembly 4 to move, move the truss to a designated position, and adjust the truss to a suitable position through the flexible movement characteristics of the Mecanum wheel 44;

[0048] S3: When the truss needs to be fixed, the Mecanum wheel 44 stops moving, at this time the hydraulic cylinder rotating block 57 provides hydraulic power to retract the diagonal arm sleeve 58, the diagonal arm sleeve 58 and the large arm 52 and the side plate 43 form a crank connecting rod system, the large arm 52 is pressed down, so that the support plate 55 is tightly adapted to the ground under the pressure of the large arm 52, increasing the contact area with the ground, increasing the load and stability of the platform vehicle assembly 4;

[0049] S4: When the truss needs to be removed, the hydraulic cylinder rotating block 57 lifts the diagonal arm sleeve 58, the large arm 52 and the support plate 55 are lifted, at this time the Mecanum wheel 44 contacts the ground and starts to rotate, driving the truss to translate.

[0051] Secondly: the drawings of the disclosed embodiments of the present application only involve the structures involved in the disclosed embodiments of the present application, other structures can refer to the usual design, in the case of no conflict, the same embodiment and different embodiments of the present application can be combined with each other;
