[0013] As Figure 2 And Figure 3 Indicated, base 81 includes base plate 811, and base plate 811 is fixed on support table 70, two vertical plates 812 are provided on base plate 811 in parallel, positioning member 82 is detachably penetrated on two vertical plates 812, connecting plate 83 provided at the end of hydraulic cylinder 20 is sleeved on positioning member 82 and is in the gap between two vertical plates 812, and hydraulic cylinder 20 and connecting plate 83 are rotatable relative to positioning member 82. In actual design, positioning member 82 can include bolt and nut, wherein the bolt includes screw rod, the one end of screw rod is provided with bolt head, and the other end is provided with thread for screwing with nut, and the middle part of screw rod is designed without thread.

[0014] Further, in order to improve the rotation stability of hydraulic cylinder 20 and avoid friction between vertical plate 812 and connecting plate 83, rubber ring 84 is further provided between each vertical plate 812 and connecting plate 83, and rubber ring 84 is sleeved on positioning member 82.

[0015] As Figure 2 And Figure 4As shown, the connecting seat 31 comprises a bottom plate 311 fixedly connected with the connecting rod 10, and two fixed plates 312 are arranged in parallel on the bottom plate 311, and the connecting piece 32 is detachably arranged through the two fixed plates 312.

[0017] In actual design, the piston rod 21 of the hydraulic cylinder 20 performs telescopic movement, and the telescopic movement of the piston rod 21 drives the connecting rod 10 to rotate left or right (equivalent to pulling the handle 931), and at the same time, the connecting rod 10 rotates, the piston rod 21 rotates relative to the connecting rod 10 by virtue of the design that the connecting plate 33 is rotatably connected with the connecting seat 31, and at the same time, the hydraulic cylinder 20 rotates relative to the support table 70 by virtue of the design that the connecting plate 83 is rotatably connected with the base 81.

[0018] Further, in order to avoid the piston rod 21 from being hindered during the rotation relative to the connecting rod 10, the distance between the connecting plate 33 arranged between the two fixed plates 312 and the bottom plate 311 should be designed to be large enough.

[0019] In actual design, as shown in the figure, Figure 2 The end of the connecting rod 10 is connected with the end of the pullout shaft 93 extending out of the shell 92 in a spline connection mode and is locked by the screw 60. Specifically, the end of the pullout shaft 93 is designed with external splines, the connecting rod 10 is provided with a connecting hole (not shown in the figure) in which an internal spline is designed, and the end of the pullout shaft 93 and the connecting rod 10 is provided with a screw hole (not shown in the figure). Here, the spline connection mode between the pullout shaft 93 and the connecting rod 10 ensures the movement stability during the rotation of the pullout shaft 93 driven by the connecting rod 10.

[0020] In actual application, if the operating valve 40 reserved on the hydraulic system 95 is occupied, another operating valve can be additionally arranged to achieve it.

[0021] The utility model discloses an improved XY-44 type drilling machine, that is, the original handle 931 is removed, and a connecting rod 10 is installed, the connecting rod 10 is driven by a hydraulic cylinder 20, and the original hydraulic system 95 is used to realize the control, the original manual handle is replaced by the hydraulic drive mode, in other words, the clutch realizes the power transmission and disconnection by the hydraulic drive mode, which is labor-saving, reliable and stable.

[0022] Here, the clutch used by the original XY-44 type drilling machine is a normally open single-piece dry friction clutch. The hydraulic system 95 of the XY-44 type drilling machine itself includes a hydraulic oil tank 61, a hydraulic pump 62 and a motor 63, and in addition to the original multiple control valves 40', at least one control valve 40 is usually reserved in the unused standby state. Therefore, it is feasible to improve the original hydraulic system 95 to realize the oil supply drive to the hydraulic cylinder 20.

[0023] In the utility model, the motor 63 should be selected according to the operating load and speed conditions, and the hydraulic pump 62 should be selected according to the required flow and pressure of the pumped hydraulic oil. In summary, by reasonably selecting the appropriate motor 63 and hydraulic pump 62, the action amplitude or the extension distance of the piston rod 21 of the hydraulic cylinder 20 can be controlled, and in addition, by adjusting the initial length of the piston rod 21 extending out of the hydraulic cylinder 20, the connecting rod 10 connected to the piston rod 21 is in a vertical state (i.e. the initial position, such as Figure 2 ), so that the piston rod 21 can realize the same effect as the traditional manual handle in controlling the left / right rotation of the pull fork shaft 93, which can be understood with reference to Figure 2 .

[0024] In addition, in addition to the pull fork shaft 93 and the pull fork 94 shown in Figure 1 and Figure 2 , a series of components for realizing the disconnection and connection of the clutch are designed in the housing 92, such as the loose sleeve, the ball bearing, the loose support ring, the supporting leg, the pressing leg, the pressing leg pin, the driving disc, the friction plate, the static and dynamic disc and the driving disc, which are all original components of the existing XY-44 type drilling machine, and will not be described in detail here. The specific structure, working principle and the like of the XY-44 type drilling machine can be referred to related tool books and web pages, and the XY-44 type drilling machine is an existing drilling machine product in the field, which will not be described here.

[0025] In use, the control valve 40 is controlled, the motor 63 is started, the motor 63 drives the hydraulic pump 62 to operate, the hydraulic pump 62 pumps the hydraulic oil in the hydraulic oil tank 61 into the hydraulic cylinder 20 through the oil inlet pipe 51, and then the piston rod 21 performs the retracting action (retracts the set distance). The connecting rod 10 is rotated to the left (the relative rotation between the base 81 and the hydraulic cylinder 20 and the connecting plate 83, and the relative rotation between the connecting seat 31 and the piston rod 21 and the connecting plate 33) from the vertical state (or the initial position), so that the connecting rod 10 drives the yoke shaft 93 to rotate, the yoke 94 in the cover 92 rotates through the elastic sleeve, the ball bearing, the elastic support ring and the supporting foot, and the presser foot is pressed to rotate when the presser foot cannot continue to rotate, the dynamic disc is pressed tightly through the presser foot pin, then the friction plate is tightly attached to the static and dynamic discs and the power transmission is realized through the driving disc, that is, the clutch realizes the power transmission from the power machine to the gearbox. Conversely, the control valve 40 is controlled in the opposite direction, the motor 63 and the hydraulic pump 62 stop operating, the hydraulic oil in the hydraulic oil tank 61 returns to the hydraulic cylinder 20 through the oil return pipe 52, and then the piston rod 21 performs the extending action (extends the predetermined distance). Then, the piston rod 21 drives the connecting rod 10 to rotate to the right (the relative rotation between the base 81 and the hydraulic cylinder 20 and the connecting plate 83, and the relative rotation between the connecting seat 31 and the piston rod 21 and the connecting plate 33), so that the connecting rod 10 drives the yoke shaft 93 to rotate in the opposite direction, the dynamic disc is pushed away from the friction plate by the spring force to generate a gap, and then the power is disconnected, that is, the clutch disconnects the power transmission between the power machine and the gearbox.

[0026] Therefore, the clutch power transmission and disconnection realized by the worker manually pulling the handle is changed into the worker controlling the control valve of the original hydraulic system, the power transmission and disconnection are realized by the hydraulic cylinder driving mode, labor is saved, the control is timely and reliable, the drilling operation of the drilling machine can be effectively matched, the drilling operation is ensured to be smoothly performed, and the construction safety is improved.
