Description

Technical Field

[0001] The utility model relates to the technical field of raise boring machines, and specifically relates to a guiding structure of a raise boring machine. Background Technique

[0002] A raise boring machine is a drilling device widely used in engineering. The hob on the pilot hole bit or the reaming bit makes pure rolling or micro-sliding along the working surface of the rock at the bottom of the well under the action of the drilling pressure, realizing the impact, extrusion and shearing effects on the rock, and finally breaking the rock. The guiding structure of the raise boring machine is the key part to ensure that the bit can drill along the predetermined trajectory during the drilling process. Its guiding structure is mostly in the form of a guide rail, and guiding components are installed on the support. When the common guide rail is installed at the guiding place, due to the large force at the bit, it is easy to cause damage to the force at the guiding place, affecting the use effect of the guide rail, and the fixed integral frame shape is not conducive to the integral processing of the guiding place.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] See also Figures 1-6 A guide structure of a raise drilling rig includes a pillar 1, a guide groove 5, an adapter seat 7, a fixed seat 8 and a connecting plate 9. More than one pillar 1 is connected by a plurality of connecting plates 9. A fixed seat 8 is arranged in the middle area relative to the pillar 1. A plurality of guide grooves 5 are arranged at the opposite ends of the pillar 1. An adapter seat 7 is arranged at the opposite ends of the pillar 1. Both ends of the adapter seat 7 can slide inside the guide groove 5 of the pillar 1. A plurality of fixed seats 8 are arranged in the middle area relative to the pillar 1. The fixed seat 8 is connected to the connecting plate 9. The guide groove 5 on the pillar 1 is processed by a milling machine to ensure the roughness and parallelism of the inner wall of the guide groove 5 to adapt to the guiding effect applied to the guide rail. The pillar 1 is preferably made of steel. The fixed seat 8 and the connecting plate 9 are connected by bolts, and the connecting plate 9 and the pillar 1 are connected by bolts. The adapter seat 7 slides on the pillar 1, and the adapter seat 7 cooperates with the guide groove 5 to effectively realize the effect of guiding the movement of the adapter seat 7, and the pillars 1 are connected by the connecting plate 9 to improve the connection effect between the pillars 1. The connection support effect between the pillars 1 is strengthened by the fixed seat 8, and the position deviation of the pillar 1 is reduced. This form of connection is adopted, and the guide groove 5 on the pillar 1 guides the movement of the adapter seat 7, and the characteristics of the guide groove 5 on the pillar 1 can be directly processed, providing better guiding effect and support strength, providing better guiding positioning support effect, and facilitating processing.

[0028] Reference Figure 1 The guide structure also includes a weight-reducing groove 3. The opposite ends of the plurality of pillars 1 are provided with the weight-reducing groove 3. By providing the weight-reducing groove 3, the weight of the pillar 1 is reduced and the installation of some other structural parts is facilitated.

[0029] Reference Figure 1 and 6 This guide structure also includes a through hole 4, and each pillar 1 is provided with a through hole 4. By providing the through hole 4, the weight of the pillar 1 is reduced, and the sensor and other components for detecting the position of the adapter 7 can be installed inside the through hole 4, so as to facilitate the position detection of the adapter 7.

[0030] Reference Figure 1, this guiding structure further includes a reinforcing plate 2. A number of struts 1 are connected by a number of reinforcing plates 2. The cross-section of the reinforcing plate 2 is in a shape of "ji", and the connection effect between the struts 1 is enhanced through the reinforcing plate 2, improving the supporting strength of the struts 1. The use of this "ji" shape for the reinforcing plate 2 is beneficial to the installation of the reinforcing plate 2 and can leave a relatively large space for installing other components.

[0031] Refer to Figure 2 and 3 , this guiding structure further includes wear-resistant plates 10. A number of wear-resistant plates 10 are provided on the inner wall of the guiding groove 5 of the adapter seat 7 facing the strut 1. The wear-resistant plates 10 are wear-resistant plates 10, and preferably wear-resistant steel plates. Through the setting of the wear-resistant plates 10, after long-term use, the wear-resistant plates 10 can be replaced to replace the contact part between the machined adapter seat 7 and the strut 1, facilitating maintenance.

[0032] Refer to Figure 3 , this guiding structure further includes a relief groove 6. A relief groove 6 is provided at the inner wall corner of the guiding groove 5 of the strut 1. Through the setting of the relief groove 6, a part of the space can be left for installing the adapter seat 7, reducing the interference between the corner of the adapter seat 7 and the corner of the guiding groove 5.

[0033] Refer to Figure 2 and 3 , the adapter seat 7 is provided with a protruding part corresponding to the guiding groove 5. Grooves matching the side walls of the strut 1 are provided on both sides of the protruding part of the adapter seat 7. The protruding part of the adapter seat 7 is inserted into the inside of the guiding groove 5. Through the cooperation between the protruding part of the adapter seat 7 and the strut 1, the cooperation effect between the strut 1 and the adapter seat 7 is improved, which is beneficial to supporting the strut 1 and improving the guiding effect.

[0034] Among them, the surface roughness of the guiding groove 5 on the strut 1 is less than Ra6.3, and the end face roughness of the opposite ends of the strut 1 is less than Ra6.3. Through the lower roughness, wear is reduced, which is beneficial to the sliding fit between the strut 1 and the adapter seat 7.

[0035] Refer to Figure 5 , both ends of the fixed seat 8 are inserted into the inside of the guiding groove 5, and the outer wall of the fixed seat 8 contacts the inner wall of the guiding groove 5. Through the cooperation between both ends of the fixed seat 8 and the guiding groove 5 on the strut 1, the connection stability between the strut 1 and the fixed seat 8 is improved, and the guiding stability effect on the adapter seat 7 is improved.

[0036] During use, the strut 1 is installed on the raise boring machine, the adapter seat 7 is connected to the driving device on the boring machine, and the drilling and tapping component of the boring machine is installed on the adapter seat 7.
