Embodiment Construction

[0010] see figure 1 , figure 1 It is a structural schematic diagram of the transmission case of the rock bolter with vibration of the present invention. Depend on figure 1 It can be seen that the transmission case of the rock bolter with vibration of the present invention comprises a transmission case 14, and a gear shaft 24 is vertically installed with a bearing 23 and a bearing sleeve 27 in the transmission case 14 and with a bearing 15, a cylindrical roller A main shaft 4 is installed on the sub-bearing 10, retaining ring 9 and seal ring 7, and a driving gear 26 is installed on the gear shaft 24 with a key 25, and a driven gear 16 is installed on the lower end of the main shaft 4 with a key 21 and a retaining ring 22. The driven gear 16 meshes with the gear shaft 24, and the middle of the main shaft 4 is sequentially set with a fixed ratchet 13 and a movable ratchet 11. The fixed ratchet 13 is fixedly connected to the inner wall of the transmission box 14 with a hexagonal...

Abstract

The invention relates to a transmission case body with a vibratory anchor drill, which is used for anchor bolt support operation of tunnels in coal mines. The transmission case body with a vibratory anchor drill comprises a transmission base body (14) in which a gear shaft (24) and a main shaft (4) are arranged, wherein the upper end of the main shaft (4) is provided with a drill bushing (1); the transmission base body (14), a water jacket (6) and the drill bushing (1) are externally provided with a rear mud fender (29) which is externally provided with a hose clamp (28); the middle of the main shaft (4) is sequentially sleeved with a fixed ratchet (13) and a movable ratchet (11) from bottom to top; the fixed ratchet (13) is fixedly connected to the inner wall of the transmission base body (14); an offsetting spring (12) is embedded in an inner cavity formed by the fixed ratchet (13) and the movable ratchet (11) and sleeved on the main shaft (4); and the fixed ratchet (13) and the movable ratchet (11) form a double-ratchet assembly. The invention realizes vibration depending on the ratchet assembly which is arranged on the main shaft and also achieves the function of rotation with impaction, and therefore, the drilling speed is high.

Description

(1) Technical field [0001] The invention relates to a rock bolter. Specifically relates to a transmission box of a rock bolter. It belongs to the technical field of coal mine machinery. (2) Background technology [0002] Bolting rigs are used for bolting operations in coal mine roadways. It can not only drill the roof anchor hole, but also drill the anchor cable hole, and can also stir and install the resin coil type anchor rod and anchor cable. Without other equipment, the anchor nut can be installed and tightened at one time. The rock bolt rig has the characteristics of small size, light weight, simple operation and convenient maintenance. The rock bolt rig adopts a gear motor with stable operation and high reliability. The transmission box of a rock bolter is generally composed of a transmission box, a gear shaft, a driving gear, a passive gear, a main shaft, a water jacket and a drill sleeve. It mainly has the following disadvantages: it does not have an impact effe...
