Technical Field

[0001] The utility model relates to the technical field of automatic oil replenishing structures, in particular to a gear box for an anchor bolter with automatic oil replenishing effect. Background Art

[0002] Anchor drilling rig is a drilling machine used for engineering anchoring. It uses rotary drilling to drill holes at designated locations and then performs anchoring. It is one of the commonly used drilling methods in many projects today. In order to ensure smooth anchor drilling, the rotation speed needs to be adjusted, which requires the use of a corresponding gearbox for adjustment.

[0003] In order to ensure the service life and operational stability of the gear set in the gearbox, it is necessary to add lubricating grease to reduce the friction during the gear meshing rotation process, thereby reducing the wear rate of the gear and increasing the service life. The current method of adding lubricating grease is to expose the gearbox after the machine stops running, and then inject grease into the gearbox. This method will directly reduce the progress of the project, and after adding, it needs to idle for a period of time to ensure full coverage of grease, which wastes energy. For this reason, a gearbox for an anchor bolt machine with automatic oil replenishment effect is proposed. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please refer to Figure 1-4 The utility model relates to a gearbox for an anchor bolter with an automatic oil replenishing effect, comprising a gearbox body 1, an oil storage tank 2 is provided above the gearbox body 1, a delivery pipe 3 is fixedly connected to the middle of the side wall opposite to the gearbox body 1, a connecting pipe 9 is fixedly connected to the middle of the bottom side wall of the oil storage tank 2, the connecting pipe 9 is inserted into the delivery pipe 3, and a guide plate 10 and a control plate 12 are fixedly connected to the inner walls of the delivery pipe 3 near both ends, the guide plate 10 and the control plate 12 are both semi-conical structures, a semicircular tubular structure is opened at the bottom end of the guide plate 10, and a parallel structure is formed at the bottom end of the control plate 12, an adjusting plate 4 and a pulling plate 5 are telescopically inserted on one side of the delivery pipe 3 near both ends, and one end of the adjusting plate 4 and the pulling plate 5 extending into the delivery pipe 3 is fixedly connected with a semi-conical structure corresponding to the guide plate 10 and the control plate 12;

[0017] A spherical transfer ball 7 is fixedly connected to the middle of the conveying pipe 3. The transfer ball 7 is a hollow structure and communicates with the inside of the conveying pipe 3. The edge of the transfer ball 7 opposite to the control plate 12 is fixedly connected to a conical plate 11. The side wall of the adjustment plate 4 and the pulling plate 5 away from the conveying pipe 3 is fixedly connected to a handle 15. The bottom side wall of the adjustment plate 4 close to the handle 15 is fixedly connected to a lower extension plate 13. The top side wall of the pulling plate 5 close to the handle 15 is fixedly connected to a vertical plate 14. The end of the vertical plate 14 away from the pulling plate 5 is located between the lower extension plate 13 and the conveying pipe 3 and is in contact with the side wall of the lower extension plate 13.

[0018] The technical effect of this solution is as follows: the oil stored in the oil storage tank 2 will enter the delivery pipe 3 along the connecting pipe 9, and will first be injected into the guide plate 10, and then flow into the transfer ball 7 through the bottom of the guide plate 10, and finally flow into the control plate 12 along the conical plate 11, and then the grease will continue to flow downward through the gap of the control plate 12 and finally enter the injection plate 8. The grease flows and diffuses along the slope in the injection plate 8, and finally flows to the corresponding gear through the opened oil leakage hole 16, realizing the function of oil filling and lubrication. The whole process does not require shutdown or manual operation, because oil filling can be achieved during operation, so there is no need for running-in after oil filling like the traditional process, and the injection amount can be adjusted by setting up the guide plate 10, conical plate 11 and control plate 12 to avoid the problem of waste caused by excessive injection.

[0019] An inner cavity 6 is opened inside the gear box body 1, and an injection plate 8 is fixedly connected to the top side wall of the inner cavity 6. The injection plate 8 is an arc-shaped structure, and the bottom side wall of the injection plate 8 corresponds to the gear set in the inner cavity 6. The end of the delivery pipe 3 away from the oil storage tank 2 extends into the inner cavity 6 and is fixedly connected to the top side wall of the injection plate 8. The interior of the injection plate 8 is a hollow structure and is communicated with the interior of the delivery pipe 3. The bottom side wall of the injection plate 8 is staggered and penetrated with oil leakage holes 16, and a filter screen 17 is embedded in the oil leakage hole 16. The position of the oil leakage hole 16 corresponds to the gear.

[0020] The technical effect of this solution is: because the gears in the gearbox need to assume the function of speed regulation, there are certain requirements for the position distribution of the gears. In order to ensure that all gears can be lubricated, corresponding oil leakage holes 16 are opened on the injection plate 8 according to the position of the gears, which can ensure that the oil is accurately poured on the gears, thereby realizing the function of efficient oiling and lubrication.

[0021] Specifically, when the utility model is used, the grease in the oil storage tank 2 is injected into the delivery pipe 3 through the connecting pipe 9, and finally enters the injection plate 8 through the guide plate 10, the conical plate 11 and the control plate 12 in sequence and is poured on the gear through the oil leakage hole 16. During the grease delivery process, the adjustment plate 4 and the pulling plate 5 are pulled as needed to drive the semi-conical structure corresponding to the guide plate 10 and the control plate 12 to move, thereby adjusting the distance between the guide plate 10 and the control plate 12 and adjusting the flow rate. When the control plate 12 is adjusted, the adjustment plate 4 can be adjusted synchronously, and the adjustment plate 4 can be adjusted independently, and when fully closed, the control plate 12 will be sealed, but the guide plate 10 will leave a minimum number of holes due to its structure to ensure continuous oil delivery. After closing, the grease continues to accumulate. In order to increase the capacity, a transfer ball 7 is set up to temporarily store the grease. In this way, after opening for delivery, the grease can be poured on the gears as quickly as possible, reducing the waiting time for lubrication. The grease in the oil storage tank 2 can be extended out through the pipeline and replenished regularly. The filter screen 17 can achieve a dripping effect to ensure the uniformity of grease pouring.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
