[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. 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.

[0023] like Figures 1 to 3As shown, an embodiment of the present application provides an installation device for a hydraulic motor mechanical transmission group. The installation device is installed between a hydraulic motor base connecting steel plate 10 and a pier top connecting steel plate 20. The installation device includes an adjusting screw 30, a first nut 40 and a second nut 50.

[0024] The adjusting screw rod 30 is inserted between the hydraulic motor base connecting steel plate 10 and the pier top connecting steel plate 20. The first nut 40 is arranged on the adjusting screw rod 30. The second nut 50 is arranged on the adjusting screw rod 30 and is located on both sides of the hydraulic motor connecting steel plate with the second nut 50. The first nut 40 and the second nut 50 can rotate on the adjusting screw rod 30.

[0025] A connection hole 60 is provided on the hydraulic motor base connection steel plate 10, and an adjustment hole 70 is provided on the pier top connection steel plate 20. The connection hole 60 and the adjustment hole 70 are used for bolts to pass through. Specifically, the connection hole 60 is a circular hole, and the adjustment hole 70 is a strip hole. The structure of the strip hole facilitates fine adjustment of the bolt.

[0026] During installation, in order to ensure stable installation, the first nut 40 is arranged above the second nut 50 and the number of the first nuts 40 is less than the number of the second nuts 50. In this application, one first nut 40 is arranged and two second nuts 50 are arranged, wherein one second nut 50 is configured as an adjusting nut and the other second nut 50 is configured as a fixing nut. The fixing nut is located below the adjusting nut.

[0027] In order to facilitate the installation of the adjusting screw rod 30, a first mounting hole 80 is provided on the hydraulic motor base connecting steel plate 10, and the adjusting screw rod 30 is partially located in the first mounting hole 80. A second mounting hole 90 is provided on the pier top connecting steel plate 20, and the adjusting screw rod 30 is partially located in the second mounting hole 90. The first mounting hole 80 and the second mounting hole 90 correspond to each other up and down. Specifically, the size of the first mounting hole 80 is the same as the size of the second mounting hole 90, and the number of the first mounting holes 80 is the same as the number of the second mounting holes 90. Correspondingly, the number of the adjusting screw rod 30 is also the same as the number of the first mounting hole 80 and the second mounting hole 90.

[0028] In the present application, four first mounting holes 80 are provided, four second mounting holes 90 are provided, and four adjusting screw rods 30 are provided. The first mounting holes 80 are distributed in a rectangular shape, and the second mounting holes 90 are also distributed in a rectangular shape.

[0030] Step 1. Turn the adjusting nut so that the unit is roughly level.

[0031] Step 2. Place the adjustment hole 70 along the center direction of the ball joint at the position of the reserved hole on the pier top and initially fix it by bolt connection.

[0032] Step 3. Fix the hydraulic motor mechanical transmission group to the device by bolting.

[0033] Step 4. Turn the adjusting nut to adjust the horizontal height of the hydraulic motor to ensure that there is enough reserved space for the gear and arc rack on the top of the hydraulic motor.

[0034] Step 5. Loosen the bolts at the adjustment hole 70 appropriately, and fine-tune the horizontal position of the device so that the gear on the hydraulic motor and the arc-shaped rack engage with each other with an appropriate gap. After confirming that there is no error, tighten the bolts to fix it.

[0035] Step 6. Fine-tune the adjusting nut again to make the hydraulic motor level.

[0036] Step 7. Rotate the first nut 40 on the top of the device and the fixing nut below the adjusting nut to lock the adjusting system of the device and complete the entire installation of the device.

[0037] In summary, the installation device of the hydraulic motor mechanical transmission group of the present application has the following beneficial effects:

[0038] 1. When the reserved hole position deviates, resulting in the hydraulic motor being unable to be installed normally or the gear and rack conflicting after installation, the adjustment hole 70 on the device can be used for horizontal fine adjustment to return the hydraulic motor to the correct working position, ensure the mutual engagement of the gear and rack, and ensure the normal operation of the hydraulic motor mechanical transmission group.

[0039] 2. The installation device is flexible and adjustable, easy to operate, and effectively reduces the difficulty of installing the hydraulic motor; at the same time, it is easy to dismantle and reuse.

[0040] 3. The device can be adjusted horizontally by adjusting the nut, avoiding the problem of unevenness after the hydraulic motor is installed; at the same time, the height of the hydraulic motor can also be adjusted, reducing the accuracy requirements for elevation measurement during direct installation.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
