Description

Technical Field

[0001] This utility model relates to a track leveling and calibration mechanism, specifically, to a track leveling and calibration mechanism for a gantry crane. Background Technology

[0002] A truss crane is a lifting device with a truss structure as its core load-bearing component. It features high strength, lightweight, and large span. During operation, a truss crane relies on multiple track systems, including the top moving track and horizontal moving track. To ensure the stability of the truss crane's operation, the tracks are fixed to the top of the truss crane with bolts and clamps. During use, the tracks must be kept precisely level. However, during the installation of the top track, due to its length and high installation position, multiple workers are required to coordinate the leveling operation. This not only increases labor costs but also easily leads to inconsistent adjustment at both ends of the track due to asynchronous operations. Furthermore, workers find it difficult to determine whether the track is level during leveling, severely impacting the efficiency of track leveling. Therefore, we propose a truss crane track leveling and calibration mechanism. Utility Model Content

[0003] The purpose of this utility model is to provide a track leveling and calibration mechanism for truss cranes to solve the problems mentioned in the background art.

[0004] To address the aforementioned problems, the present invention aims to provide a gantry crane track leveling and calibration mechanism, comprising an adjustment mechanism and a rotation mechanism. The adjustment and rotation mechanisms are used to adjust the horizontal state of the track body 3 at the top of the gantry crane. The adjustment mechanism drives the track body to rotate around the rotation mechanism. The adjustment mechanism includes a first mounting bracket bolted to one end of the track body. Two transmission components are arranged on the side of the first mounting bracket away from the track body. The transmission components drive the first mounting bracket to move the track body. A rotating plate is rotatably connected to the first mounting bracket, and a level is mounted on the rotating plate. During use, the level is parallel to the track body, facilitating observation by operators to ensure the track body is rotated to a horizontal state.

[0005] As a further improvement to this technical solution, the transmission assembly includes a first rotating frame rotatably connected to the side of the first mounting frame away from the track body. An adjusting block is rotatably connected inside the first rotating frame, and a threaded rod is threadedly connected inside the adjusting block. During rotation, the threaded rod drives the adjusting block to move along the axial direction of the threaded rod.

[0006] As a further improvement to this technical solution, the two ends of the threaded rod pass through the adjusting block and extend outwards. One end of the threaded rod is provided with a connecting piece. The adjusting mechanism also includes a first mounting plate disposed below one side of the track body. The connecting piece connects the threaded rod to the first mounting plate.

[0007] As a further improvement to this technical solution, the connector includes a second rotating frame rotatably connected to the first mounting plate, a rotating block rotatably connected inside the second rotating frame, and the end of the threaded rod near the first mounting plate rotatably connected to the rotating block via a bearing.

[0008] As a further improvement to this technical solution, a knob is fixedly connected to the end of the threaded rod away from the rotating block, and two bellows tubes are movably sleeved on the threaded rod. The two ends of one bellows tube are fixedly connected to the rotating block and the adjusting block respectively, and the two ends of the other bellows tube are fixedly connected to the knob and the adjusting block respectively. The bellows tubes are used to block dust from adhering to the surface of the threaded rod and prevent dust from accumulating on the surface of the threaded rod and affecting the movement of the adjusting block.

[0009] As a further improvement to this technical solution, the rotating mechanism includes a second mounting bracket bolted to the other end of the track body, a second mounting plate disposed below one side of the second mounting bracket, and a driven component disposed on the second mounting plate, the driven component connecting the second mounting bracket and the second mounting plate together.

[0010] As a further improvement to this technical solution, the driven component includes a support plate fixedly connected to the second mounting plate. The support plate has a rotating groove that passes through the support plate. A turntable is rotatably connected inside the rotating groove. A limiting groove is formed on the arc surface of the turntable, and the arc surface of the rotating groove is located inside the limiting groove.

[0011] As a further improvement to this technical solution, a fixing frame is fixedly connected to the side of the turntable near the second mounting frame, and a fixing block fixed on the second mounting frame is rotatably connected inside the fixing frame, thereby connecting the second mounting frame and the turntable together through the fixing frame and the fixing block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This gantry crane track leveling and calibration mechanism initially installs the track body on top of the gantry crane by setting up an adjustment mechanism and a rotation mechanism. At the same time, the operator installs a level on the adjustment mechanism, making the level parallel to the track. Then, the operator drives the adjustment mechanism to rotate one end of the track body around the rotation mechanism, causing the inclined track to rotate towards a horizontal state. During the rotation of the track body, the operator can easily observe whether the track is horizontal through the level. At the same time, it eliminates the need for multiple operators to cooperate in leveling the track body, thereby improving the efficiency of track leveling and reducing labor costs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figure 1 and Figure 2 As shown, the purpose of this embodiment is to provide a gantry crane track leveling and calibration mechanism, including an adjustment mechanism 1 and a rotation mechanism 2. The adjustment mechanism 1 and the rotation mechanism 2 are used to adjust the horizontal state of the track body 3 at the top of the gantry crane. The adjustment mechanism 1 drives the track body 3 to rotate around the rotation mechanism 2, allowing the track body 3 to be adjusted in multiple directions to ensure that the track body 3 can maintain a horizontal state. The adjustment mechanism 1 includes a first mounting bracket 11 bolted to one end of the track body 3. Two transmission components are arranged on the side of the first mounting bracket 11 away from the track body 3. The transmission components drive the first mounting bracket 11 to move the track body 3. A rotating plate 12 is rotatably connected to 11. A level 13 is installed on the rotating plate 12. The level 13 can be a two-dimensional electronic level of model TS75-2D-120. The two-dimensional electronic level measures the small tilt angle of the measured surface relative to the horizontal plane based on the balance principle of capacitive pendulum. It can detect the tilt angle of the horizontal plane of the track body 3 from all directions. The level 13 is an existing product and will not be described here. The rotating mechanism 2 includes a second mounting bracket 21 bolted to the other end of the track body 3. A second mounting plate 22 is provided on the lower side of the other side of the track body 3. A driven component is provided on the second mounting plate 22. The driven component connects the second mounting bracket 21 and the second mounting plate 22 together.

[0029] Workers use bolts to install the first mounting bracket 11 and the second mounting bracket 21 at both ends of the track body 3. Then, workers use a crane to lift the track body 3 and transfer it to the top of the truss crane. At this time, workers use bolts to install the first mounting plate 14 and the second mounting plate 22 on the top of the truss crane, so that the adjusting mechanism 1 and the rotating mechanism 2 can install the track body 3 on the top of the truss crane. At the same time, workers install the level 13 on the rotating plate 12 so that the level 13 is parallel to the track body 3.

[0030] The operator rotates the rotating plate 12 to make the level 13 parallel to the track body 3. The operation process is as follows: The operator controls two transmission components to drive the first mounting frame 11, which in turn moves one end of the track body 3. During the process of driving the first mounting frame 11, the extension of the two transmission components is adjusted according to the tilt angle of the track body 3. When the track body 3 is installed, the two transmission components adjust one end of the track body 3 to move up and down and rotate. At this time, under the restriction of the rotating mechanism 2, the track body 3 gradually rotates and moves towards the horizontal direction to level the track body 3. During the rotation of the track body 3, the operator observes the level 13 to determine whether the track body 3 is tilted, and rotates the tilted track body 3 to the horizontal position. After the track body 3 is leveled, the operator fixes the leveled track body 3 to the top of the gantry crane with bolts and clamps, so that the track body 3 can be installed horizontally on the top of the gantry crane, reducing the probability of the track body 3 tilting during use, thereby ensuring the normal use of the track body 3.

[0031] refer to Figure 3 - Figure 5The transmission assembly includes a first rotating frame 15 rotatably connected to the first mounting frame 11 on the side away from the track body 3. An adjusting block 151 is rotatably connected inside the first rotating frame 15, and a threaded rod 152 is threadedly connected inside the adjusting block 151. During rotation, the threaded rod 152 drives the adjusting block 151 to move along its axial direction. The moving adjusting block 151 also drives the first rotating frame 15 to move, which in turn moves one end of the track body 3. During this movement, the angle between the track body 3 and the threaded rod 152 changes. During this process, the first rotating frame 15 and the adjusting block 151 rotate with the threaded rod 152, keeping the central axis of the adjusting block 151 and the threaded rod 152 aligned. Both ends of the threaded rod 152 pass through the adjusting block 151 and extend outwards. A connecting piece is provided at one end of the threaded rod 152. The adjustment mechanism 1 also includes a first mounting plate 14 located below one side of the track body 3. The connecting piece connects the threaded rod 152 to the first mounting plate 14. When the threaded rod 152 and the track body 3 rotate, the adjustment mechanism 1 moves along the track body 3. When the included angle between the main bodies 3 changes, the included angle between the threaded rod 152 and the first mounting plate 14 changes under the constraint of the connecting member. The connecting member includes a second rotating frame 153 rotatably connected to the first mounting plate 14. A rotating block 154 is rotatably connected inside the second rotating frame 153. The end of the threaded rod 152 near the first mounting plate 14 is rotatably connected to the rotating block 154 via a bearing. When the included angle between the threaded rod 152 and the first mounting plate 14 changes, the moving threaded rod 152 drives the rotating block 154. 54. The second rotating frame 153 rotates to keep the central axis of the threaded rod 152 and the rotating block 154 coincide. During the rotation of the rotating block 154, the threaded rod 152 is driven to move with the adjusting block 151, so as to keep the central axis of the adjusting block 151 and the threaded rod 152 coincide. This avoids the angle between the adjusting block 151 and the threaded rod 152 from changing, which would cause the threads on the adjusting block 151 and the threaded rod 152 to rub tightly against each other, causing the threaded rod 152 to jam. This allows the threaded rod 152 to rotate normally.

[0032] Among them, a knob is fixedly connected to one end of the threaded rod 152 away from the rotating block 154, and two bellows tubes 155 are movably sleeved on the threaded rod 152. The two ends of one bellows tube 155 are fixedly connected to the rotating block 154 and the adjusting block 151 respectively, and the two ends of the other bellows tube 155 are fixedly connected to the knob and the adjusting block 151 respectively. The bellows tube 155 is used to prevent dust from adhering to the surface of the threaded rod 152.

[0033] The operator drives the knob to rotate using an electric wrench, causing the threaded rod 152 to rotate. Under the constraint of the first mounting bracket 11 and the first rotating bracket 15, the rotating threaded rod 152 drives the adjusting block 151 to move. During the movement, the adjusting block 151 drives one end of the track body 3 to move through the first rotating bracket 15 and the first mounting bracket 11, causing the track body 3 to rotate for leveling. During the movement, the adjusting block 151 drives the bellows tube 155 to extend and retract. The bellows tube 155 shields the threaded rod 152 to prevent dust from adhering to the threaded rod 152 and affecting the normal movement of the adjusting block 151.

[0034] refer to Figure 6 and Figure 7 The driven component includes a support plate 23 fixedly connected to the second mounting plate 22. A rotating groove is provided on the support plate 23, and a turntable 24 is rotatably connected inside the rotating groove. A limit groove is provided on the arc surface of the turntable 24, and the arc surface of the rotating groove is located inside the limit groove. A fixing frame 26 is fixedly connected to the side of the turntable 24 near the second mounting frame 21. A fixing block 25 fixed to the second mounting frame 21 is rotatably connected inside the fixing frame 26. The second mounting frame 21 and the turntable 24 are connected together through the fixing frame 26 and the fixing block 25. When the track body 3 rises or falls near the end of the adjusting mechanism 1, the track body 3 rotates around the position where the fixing block 25 and the fixing frame 26 are rotatably connected. When one side of the track body 3 rises or falls, the track body 3 drives the fixing block 25 and the fixing frame 26 to rotate. The rotating fixing frame 26 drives the turntable 24 to rotate inside the rotating groove.

[0035] When using this device:

[0036] Workers use a crane to lift the track body 3, which is equipped with the adjustment mechanism 1 and the rotation mechanism 2, and install it on the top of the truss crane. Then, workers climb to the top of the truss crane and install the level 13 on the rotating plate 12. Workers rotate the rotating plate 12 to drive the level 13 to rotate, and use the level 13 to detect the axis of the track body 3 and the tilt angle of the horizontal plane perpendicular to the axis.

[0037] Subsequently, the staff used an electric wrench to turn the knob, causing the threaded rod 152 to rotate. The rotating threaded rod 152 caused the adjusting block 151 to move, which in turn caused the track body 3 to rotate, simultaneously rotating the track body 3, which was tilted on the side and end, towards a horizontal state. At the same time, the staff observed the level 13 to determine whether the track body 3 had rotated to a horizontal state, thus leveling the track body 3. After the track body 3 was leveled, it was reinforced with bolts and clamps to ensure that the track body 3 remained stable during use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
