[0003] When replacing and installing track rollers, the new track rollers can weigh tens or even hundreds of kilograms. It is very difficult for workers to lift the track rollers by themselves. Aligning the track roller's axle hole with the track frame's bushing is even more difficult. Workers also need to lift the track rollers while tightening the bolts, which is extremely inconvenient. Summary of the Invention

[0004] To overcome the inconvenience of replacing track track rollers, this invention provides a track track roller mounting device.

[0005] Technical solution: A track support roller mounting device includes a base and an auxiliary mechanism. The auxiliary mechanism includes a swing arm symmetrically and elastically hinged to the base. A sliding frame is slidably mounted on the swing arm. An electric push rod is mounted on the swing arm, and the telescopic end of the electric push rod is fixedly connected to the sliding frame. A sliding groove is provided on one side of the sliding frame, and a slider is slidably connected in the groove. A U-shaped frame is rotatably connected between two sliders. A positioning frame for placing the support roller is slidably connected horizontally on the U-shaped frame. Two sets of rotating rods are movably connected through the positioning frame. The rotating rods have grooves for placing bolts. A positioning mechanism for positioning the installation position of the support roller is provided on one side of the positioning frame. The positioning mechanism includes elastic positioning pins symmetrically arranged on one side of the U-shaped frame.

[0006] In a preferred embodiment of the present invention, the positioning mechanism further includes a T-shaped frame fixed to the sliding frame, and positioning blocks are symmetrically and elastically slidably connected to the T-shaped frame.

[0007] In a preferred embodiment of the present invention, the positioning mechanism further includes a damping telescopic rod fixedly connected to the U-shaped frame, wherein the telescopic end of the damping telescopic rod is fixedly connected to the positioning frame.

[0008] In a preferred embodiment of the present invention, the positioning mechanism further includes a guide frame fixedly connected to the positioning frame, a rectangular frame elastically slidably sleeved on the guide frame, through slots symmetrically opened on the rectangular frame, a movable block slidably connected in the through slots, and the fixed end of the elastic positioning pin being fixedly connected to the movable block.

[0009] In a preferred embodiment of the present invention, guide grooves are symmetrically provided on the guide frame, and the movable block is slidably inserted into the guide grooves.

[0010] In a preferred embodiment of the present invention, an elastic limiting pin is elastically slidably connected through the guide frame, and a pull rod is fixedly connected to the rectangular frame, wherein the pull rod has a pin hole that matches the elastic limiting pin.

[0011] In a preferred embodiment of the present invention, a bidirectional lead screw driven by a drive motor is rotatably connected to the base, a scissor lift frame threadedly connected to the bidirectional lead screw is mounted on the base, a top rod is slidably connected through the scissor lift frame, and a crossbar cooperating with the top rod is fixedly connected between the two sliding frames.

[0012] In a preferred embodiment of the present invention, a connecting block is fixedly sleeved on the slider, a rack is fixedly connected to the connecting block, a gear that meshes with the rack is rotatably connected to the sliding frame, a pull rope is wound around the shaft of the gear, a pull ring is fixedly connected to the end of the pull rope, and a pair of guide wheels are rotatably mounted on the sliding frame, with the pull rope wound around the guide wheels.

[0013] In a preferred embodiment of the present invention, a strip block is fixedly connected to the rack, and an elastic wedge block that cooperates with the strip block is elastically slidably connected inside the sliding frame.

[0014] In a preferred embodiment of the present invention, a lever plate is fixedly connected to the elastic wedge block and slidably connected to the sliding frame.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The present invention, through the design of the auxiliary mechanism, allows the sliding frame to slide upward along the swing arm. During the subsequent installation of the support roller, the slider slides along the groove of the sliding frame, which moves the support roller to the installation position on the track frame. By allowing the positioning frame to slide along the U-shaped frame, the elastic positioning pin can be inserted into the bolt hole of the track frame, thereby achieving precise positioning of the support roller installation position.

[0017] 2. Through the design of the rectangular frame and guide groove, after the elastic positioning pin is inserted into the bolt hole of the track frame, the worker can pull the pull rod downward to make the two elastic positioning pins avoid the bolt hole of the track frame, so that the bolt can be easily inserted into the bolt hole of the track frame.

[0018] 3. Through the design of gears and racks, this invention allows the support roller to move to abut against the track frame by pulling the pull ring after the elastic positioning pin avoids the bolt holes of the track frame, and then the bolts can be tightened by rotating the rotating rod.

Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0034] Example 1

[0035] A track track roller mounting device, such as Figures 1-3 As shown, the system includes a base 1 and an auxiliary mechanism. The auxiliary mechanism includes a swing arm 201 symmetrically and elastically hinged to the base 1. A sliding frame 202 is slidably sleeved on the outer wall of the swing arm 201. A sliding groove is provided on the side of the two sliding frames 202 that are close to each other. A slider 203 is slidably connected in the sliding groove. A U-shaped frame 204 is rotatably connected between the two sliders 203. A positioning frame 205 for placing the support roller is slidably connected to the top of the U-shaped frame 204 in the horizontal direction. Two sets of rotating rods 206 are movably connected through the positioning frame 205, with two rods in each set. A groove for placing bolts is provided at the top of the rotating rods 206. A positioning mechanism for positioning the support roller installation position is provided on the rear side of the positioning frame 205. The positioning mechanism includes elastic positioning pins 207 symmetrically arranged on the rear side of the U-shaped frame 204. The elastic positioning pins 207 are used to insert into the bolt holes of the track frame.

[0036] like Figure 3 As shown, the positioning mechanism also includes a T-shaped frame 301 fixed to one side of the sliding frame 202. A positioning block 302 is symmetrically and elastically slidably connected to the T-shaped frame 301. The positioning block 302 is used to clamp the track frame.

[0037] like Figure 5 As shown, the positioning mechanism also includes a damping telescopic rod 401 fixed to the U-shaped frame 204. The telescopic end of the damping telescopic rod 401 is fixed to the positioning frame 205. When the staff moves the positioning frame 205, the damping telescopic rod 401 can keep the positioning frame 205 stable after movement.

[0038] like Figures 6-8 As shown, the positioning mechanism also includes a guide frame 501 fixed to the rear side of the positioning frame 205. A rectangular frame 502 is elastically slidably sleeved on the outer wall of the guide frame 501. A through groove is symmetrically opened on the front side of the rectangular frame 502. A movable block 503 is slidably connected in the through groove. The fixed end of the elastic positioning pin 207 is fixedly connected to the top of the movable block 503.

[0039] like Figure 7As shown, guide slots 601 are symmetrically provided on the front side of the guide frame 501. The guide slots 601 are V-shaped, and the movable block 503 slides into the guide slots 601.

[0040] like Figure 8 and Figure 9 As shown, the rear side of the guide frame 501 is elastically slidably connected with an elastic limiting pin 701, and a pull rod 702 is fixedly connected to the rectangular frame 502. The pull rod 702 has a pin hole that matches the elastic limiting pin 701. The elastic limiting pin 701 can be inserted into the pin hole to limit the pull rod 702.

[0041] Initially, the two swing arms 201 are in a vertical position, and the elastic positioning pin 207 is in a released state. When replacing and installing the support roller, the vehicle is tilted under the action of the jack or other devices, causing one side of the track frame to be suspended in the air. The track frame is tilted. First, place the entire device on the ground near the track frame. The worker inserts four bolts into the grooves at the top of the four swing arms 206, and places the support roller on the positioning frame 205, so that the four bolts are inserted into the support roller. The extension end of the electric push rod 2021 is extended. The extension end of the electric push rod 2021 drives the two sliding frames 202 upward through the support rod, and is then... The operator pushes the sliding frame 202, causing the swing arm 201 to rotate towards the track frame. The swing arm 201 elastically contracts and rotates, aligning the sliding frame 202 with the track frame. The sliding frame 202 slides upward along the swing arm 201, lifting the slider 203 via the slide groove and the positioning block 302 via the T-shaped frame 301. The two sliders 203 together lift the positioning frame 205 upward via the U-shaped frame 204. The positioning frame 205 lifts the two sets of rotating rods 206 and the guide frame 501 upward, and also lifts the support rollers upward. The guide frame 501 drives the two movable blocks 503 via the rectangular frame 502. The lifting mechanism causes the movable block 503 to lift the elastic positioning pins 207. Subsequently, the tops of the two elastic positioning pins 207 contact the bottom of the track frame. Since the elastic positioning pins 207 and the bolt holes of the track frame are initially misaligned, the elastic positioning pins 207 elastically contract and slide under pressure. Then, the two adjacent positioning blocks 302 contact the outer wall of the track frame and elastically contract and slide under the pressure of the track frame until the top center of both T-shaped frames 301 abuts against the bottom of the track frame. At this point, the extension end of the control electric push rod 2021 stops extending. The positioning blocks 302, through their cooperation with the track frame, ensure that the support rollers are positioned centered on the lower side of the track frame, using the elastic positioning pins... Taking the position 207 located to the right of the bolt hole on the track frame as an example, the operator slides the positioning frame 205 to the left along the U-shaped frame 204. The positioning frame 205 drives the two sets of rotating rods 206 and the guide frame 501 to move, and drives the support roller to move. The guide frame 501 drives the rectangular frame 502 to move, which in turn causes the two elastic positioning pins 207 to move. At the same time, the positioning frame 205 drives the telescopic end of the damping telescopic rod 401 to retract until the two elastic positioning pins 207 are aligned with the bolt hole on the track frame. The two elastic positioning pins 207 are elastically released and slide into the bolt hole, thus completing the precise positioning of the support roller installation position, which is convenient for subsequent bolt tightening.

[0042] Initially, the pin hole of the pull rod 702 is misaligned with the elastic limiting pin 701, the movable block 503 abuts against the top of the corresponding guide groove 601, and the elastic limiting pin 701 is in an extended state. After completing the above steps, the worker pulls the pull rod 702 downwards. The pull rod 702 drives the rectangular frame 502 to elastically contract and slide downwards along the guide frame 501. The through groove of the rectangular frame 502 presses against the outer wall of the movable block 503. The movable block 503 is forced to slide downwards along the corresponding guide groove 601, and drives the elastic positioning pin 207 to descend downwards until the movable block 503 slides to the corner of the corresponding guide groove 601. At this time, the elastic positioning pin 207 has slid down. After exiting the bolt holes of the track frame, the worker continues to pull the pull rod 702. The pull rod 702 continues to drive the rectangular frame 502 to slide. The movable block 503 continues to slide along the guide groove 601 under the action of the through groove of the rectangular frame 502. The two movable blocks 503 move away from each other, and the two elastic positioning pins 207 move away from each other to avoid the bolt holes of the track frame, until the pin hole of the pull rod 702 is aligned with the elastic limiting pin 701. At this time, the movable block 503 abuts against the bottom end of the corresponding guide groove 601, and the elastic limiting pin 701 elastically contracts and slides into the pin hole of the pull rod 702 to limit the pull rod 702, thereby keeping the two elastic limiting pins 701 stable.

[0043] Example 2

[0044] like Figure 10 and Figure 11 As shown, a bidirectional lead screw 801 driven by a drive motor is rotatably connected to the top of the base 1. The drive motor is installed on the front side of the top of the base 1. A scissor lift 802 threadedly connected to the bidirectional lead screw 801 is installed on the base 1. A top rod 803 is slidably connected through the scissor lift 802. A crossbar 804 cooperating with the top rod 803 is fixedly connected between the two sliding frames 202. The top rod 803 is lifted by the scissor lift 802, which can provide support for the crossbar 804.

[0045] like Figure 12 As shown, it also includes a connecting block 901 fixedly sleeved on the slider 203. A rack 902 is fixedly connected to the bottom of the connecting block 901. A gear 903 that meshes with the rack 902 is rotatably connected to the side of the two sliding frames 202 that are close to each other. A pull rope is wound on the shaft of the gear 903. A pull ring is fixedly connected to the end of the pull rope. A pair of guide wheels 904 are rotatably connected to the front side of the sliding frame 202. The pull rope is wound on the guide wheels 904.

[0046] like Figure 12 and Figure 13 As shown, a strip block 1001 is fixedly connected to the bottom of the rack 902, and an elastic wedge block 1002 that cooperates with the strip block 1001 is elastically slidably connected inside the sliding frame 202. The rack 902 can be limited by the cooperation between the elastic wedge block 1002 and the strip block 1001.

[0047] like Figure 12 and Figure 13 As shown, a lever plate 1101 that is slidably connected to the sliding frame 202 is fixed to the front side of the elastic wedge block 1002.

[0048] Initially, slider 203 is located at the bottom of the groove of sliding frame 202. When the two sliding frames 202 slide upward, they drive the crossbar 804 to move synchronously, increasing the gap between the crossbar 804 and the top rod 803. After the two elastic positioning pins 207 avoid the bolt holes of the track frame, the drive motor controls the bidirectional lead screw 801 to rotate, causing the scissor lift 802 to extend upward. The scissor lift 802 drives the top rod 803 to move upward until the top rod 803 contacts the crossbar 804. 803 provides support for the two sliding frames 202 via the crossbar 804, then pulls the two pull rings, which in turn pull the gear 903 via the pull rope. The gear 903, through the rack 902 and the connecting block 901, drives the slider 203 to slide upward along the groove of the sliding frame 202. The rack 902 drives the strip block 1001 to rise. The two sliders 203 drive the positioning frame 205 to rise via the U-shaped frame 204. The positioning frame 205 drives the support roller to rise, and this is achieved through four rotating rods. 206 causes the four bolts to lift, then the strip block 1001 contacts and presses against the wedge-shaped surface of the elastic wedge block 1002. The elastic wedge block 1002 elastically contracts and slides under pressure, causing the lever plate 1101 to slide until the support roller abuts against the track frame. At this point, the strip block 1001 passes over the wedge-shaped surface of the elastic wedge block 1002, and the elastic wedge block 1002 elastically releases and slides, causing the lever plate 1101 to slide. The bottom surface of the strip block 1001 then contacts the elastic wedge block 1002. The top surface of 2 is attached, and the elastic wedge block 1002 limits the rack 902 through the strip block 1001. The rack 902 drives the support roller to keep it against the track frame through the connecting block 901, slider 203, U-shaped frame 204 and positioning frame 205. The worker releases the pull ring and pushes the four rotating rods 206 upwards respectively. The rotating rods 206 drive the bolts to be inserted into the bolt holes of the track frame. Then, by rotating the rotating rods 206, the bolts are tightened, and the installation of the support roller is completed.

[0049] Then, the staff moves the two levers 1101 away from each other. The levers 1101, under pressure, cause the elastic wedge block 1002 to contract and slide. After sliding, the elastic wedge block 1002 no longer contacts the strip block 1001, allowing the strip block 1001 to move freely. The U-shaped frame 204, under its own weight, causes the slider 203 to slide downwards along the groove of the sliding frame 202. The slider 203, through the connecting block 901, causes the rack 902 to descend, which in turn causes the strip block 1001 to descend. The gear 903, under the action of the rack 902, rotates in the opposite direction, and the shaft of the gear 903 winds up the pull rope until the slider 203 contacts the bottom of the groove of the sliding frame 202. The levers 1101 are then released, and the elastic wedge block 1002 elastically releases and slides, causing the levers 1101 to slide. Then, the bidirectional wire is controlled by the drive motor. Reversing lever 801 causes scissor lift 802 to retract, which in turn causes push rod 803 to descend and reset. Push rod 803 no longer contacts crossbar 804. Then, the telescopic end of electric push rod 2021 is controlled to retract, causing sliding frame 202 to slide downward along swing rod 201. Two sliders 203 descend along with sliding frame 202, causing U-shaped frame 204 to descend. Positioning frame 205 descends along with U-shaped frame 204. Guide frame 501 drives two sets of rotating rods 206 to descend and reset along with U-shaped frame 204. The electric push rod 2021 is then closed, pulling elastic limit pin 701 backward. Elastic limit pin 701 extends elastically under force and slides, disengaging from pin hole of pull rod 702. Rectangular frame 502 releases elastically and slides back, causing two elastic positioning pins 207 to move and reset. Finally, swing rod 201 is released, allowing the entire device to reset.

Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
