Description

Technical Field

[0001] The utility model belongs to the field of auxiliary equipment of underground mine shaft drilling machine, and relates to a detachable and reusable bracket device of the underground mine shaft drilling machine. Background Art

[0002] The raise drill is the main equipment for the construction of underground mines such as raises and chutes. According to the process requirements, the diameter of the drilling construction can be 1.2m, 2m, 3m, 4m, etc. The main structure of the equipment is mainly composed of a power part and a working part. The main technical parameters of the 3m raise drill in the iron mine are a guide hole of 280mm, a hole expansion cutter diameter of 3000mm, a maximum drilling depth of 400m, a machine weight of 17t, a working size of 7500mm×2800mm×3820mm, and a walking mode of tires and crawlers. Before the operation, it is necessary to pour concrete at the operation site and pre-embed HM250×170 I-beams as a fixed foundation for the later working part of the equipment.

[0003] Due to the large weight and rotating load of the equipment, each work point needs to be leveled, the embedded parts are made on site and then poured with concrete. Normal operation can only be carried out after hardening. The preparation work cycle is long, and the embedded parts are one-time use and cannot be reused later. Utility Model Content

DETAILED DESCRIPTION

[0017] Definition: Transverse H-beam, H-beam is installed transversely. Longitudinal H-beam, H-beam is installed longitudinally.

[0018] Definition: Horizontal and vertical are relative nouns, and the horizontal direction is perpendicular to the vertical direction.

[0019] Definition: Screw nut refers to the combination of a screw and a matching nut.

[0020] like Figure 1 and Figure 2As shown, a detachable and reusable support device for an underground mine shaft drilling rig is installed on a leveled working surface, including: a transverse H-shaped steel and a longitudinal H-shaped steel; there are a plurality of transverse H-shaped steels, and the plurality of transverse H-shaped steels are arranged in parallel, and at least two longitudinal H-shaped steels are installed between any two adjacent transverse H-shaped steels.

[0021] In order to ensure stability, the size of the transverse H-shaped steel is larger than that of the longitudinal H-shaped steel. The spacing between the transverse H-shaped steels increases progressively.

[0022] In actual application, it is preferred that the transverse H-shaped steels and longitudinal H-shaped steels used in the bracket device are arranged in a 4-transverse and 6-longitudinal manner, that is, three gaps are formed between the four transverse H-shaped steels, and two longitudinal H-shaped steels are used to support and limit each gap.

[0023] At the same time, the two longitudinal H-shaped steels used in each gap are staggered relative to the two longitudinal H-shaped steels in another gap. In order to facilitate transportation and reuse, the two H-shaped steels HM250×175 and HM200×135 are bolted, and bolt holes need to be drilled at the connection position on the HM250×175. If the staggered arrangement is not adopted, the connection bolt holes are relatively concentrated, which will affect the strength of the H-shaped steel.

[0024] In order to ensure the overall stability, the three gaps are named the first gap, the second gap and the third gap, wherein the spacing of the first gap is smaller than that of the second gap, and the spacing of the second gap is smaller than that of the third gap; the spacing between the two longitudinal H-shaped steels in the first gap is smaller than the spacing between the two longitudinal H-shaped steels in the second gap, and smaller than the spacing between the two longitudinal H-shaped steels in the third gap. The overall bracket device consists of three gaps. After the drilling construction is completed, the bracket bears the weight of the main machine of the equipment. Since the main body of the equipment consists of two parts, the center of gravity is close to the middle hinge position, so the spacing of the first gap is set smaller, the second gap is second, and the third gap is the largest. The force points can be reasonably distributed according to the load distribution and the strength of the bracket is increased.

[0025] In order to facilitate disassembly, the transverse H-shaped steel and the longitudinal H-shaped steel are fixed with screws and nuts 11.

[0026] Example 1

[0027] In view of the cumbersome preparation work and long preparation cycle of the construction site, combined with the working characteristics of the equipment and site conditions, H-shaped steel with a specification of HM250×175 is used, cut to the appropriate size as required, and bolt connection parts are made at both ends. The bracket installation work can be completed through on-site assembly, and the working part of the equipment can be fixed on the bracket for stable work. After the construction of the work site is completed, the bolts of the bracket components can be removed and the bracket can be transferred to the next work site for installation and reuse.

[0028] First, pre-pour concrete at the work site and level it to serve as a work surface, and after solidification, build the support device of the present application on top of it.

[0029] The support device is mainly composed of two types of H-shaped steels (HM250×175 and HM200×135), wherein the transverse H-shaped steel adopts a larger specification size (HM250×175), and the longitudinal H-shaped steel adopts a smaller specification size (HM200×135).

[0030] The H-shaped steel is arranged on site in a 4-horizontal and 6-vertical manner, that is, three gaps are formed between the four horizontal H-shaped steels, and two vertical H-shaped steels are used to support and limit each gap. The two H-shaped steels are fixed with screws and nuts 11, which are locked together to form an overall structure to increase stability, and the device must be formed and maintained in a horizontal state during installation. Specifically, the connection parts of each H-shaped steel are positioned during the processing and manufacturing process to ensure that the whole is in a horizontal state after the parts are assembled. The construction site is leveled before the operation, and the bracket is leveled and fine-tuned using a horizontal device after assembly.

[0031] Four transverse H-shaped steel Figure 2 , respectively, the first transverse H-beam 1, the second transverse H-beam 2, the third transverse H-beam 3, and the fourth transverse H-beam 4. The dimensions of the transverse H-beam are 250mm high*175mm wide*5000mm long (the length can be cut), the first transverse H-beam 1 and the second transverse H-beam 2 are 525MM apart, forming the first gap; the second transverse H-beam 2 and the third transverse H-beam 3 are 650MM apart, forming the second gap; the third transverse H-beam 3 and the fourth transverse H-beam 4 are 725MM apart, forming the third gap.

[0032] The six longitudinal H-beams are 200mm high and 135mm wide (the length can be cut). The first longitudinal H-beam 5 and the second longitudinal H-beam 6 are arranged in the first gap, and the spacing between the first longitudinal H-beam 5 and the second longitudinal H-beam 6 is 1520MM. The third longitudinal H-beam 7 and the fourth longitudinal H-beam 8 are arranged in the second gap, and the spacing between the third longitudinal H-beam 7 and the fourth longitudinal H-beam 8 is 3000MM. The fifth longitudinal H-beam 9 and the sixth longitudinal H-beam 10 are arranged in the third gap, and the spacing between the fifth longitudinal H-beam 9 and the sixth longitudinal H-beam 10 is 3000MM. The remaining spacings can be determined according to the actual situation on site.

[0033] During the installation process, the four transverse H-shaped steels and the six longitudinal H-shaped steels are fixed with screws and nuts 11.

[0034] When the device is installed, the working mechanism of the raise boring machine will be placed on top of the bracket device, which can play the role of supporting and leveling the working mechanism. After the site is completed, it can be disassembled and transferred to the next work site for reuse.
