Description

Technical Field

[0001] This utility model relates to the field of stone processing equipment technology, and more specifically to a crossbeam of a bridge cutting machine with an auxiliary guiding mechanism. Background Technology

[0002] A bridge cutting machine is a common type of stone cutting equipment. It includes a crossbeam, a transverse slide rail fixedly installed on the crossbeam, a slide block slidably installed on the transverse slide rail, and a cutting device installed on the slide block. The cutting device moves laterally by sliding the slide block. The lateral movement distance of the slide block is usually directly calculated and controlled by the control system of the bridge cutting machine. The requirements for the control system are relatively high, resulting in relatively high costs.

[0003] Based on this, the market commonly uses two limiting blocks located on both sides of the slide block to control the lateral movement of the slide block on the crossbeam. The two limiting blocks are slidably installed on the transverse slide rail. When it is necessary to adjust the lateral movement distance of the slide block, external force is used to push the two limiting blocks, causing them to slide along the transverse slide rail until the desired position is reached. However, the two limiting blocks often need to be adjusted according to the size of the stone. Since there are gaps between the two limiting blocks and the transverse slide rail for them to slide relative to the transverse slide rail, the two limiting blocks are prone to wobbling and are relatively unstable when sliding. Therefore, when the two limiting blocks slide only through the transverse slide rail, the adjustment process of the two limiting blocks is relatively difficult and time-consuming, and there are gaps between the two limiting blocks and the transverse guide rail.

[0004] In view of this, this application has conducted in-depth research on this basis, resulting in this case. Utility Model Content

[0005] The purpose of this invention is to provide a bridge cutting machine crossbeam with an auxiliary guiding mechanism, which can conveniently, quickly and labor-savingly adjust the position of the two limiting blocks.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A bridge cutting machine crossbeam with an auxiliary guiding mechanism includes a crossbeam, a transverse slide rail disposed on the crossbeam, a slide block and two limiting blocks that slide in cooperation with the transverse slide rail, the two limiting blocks being disposed on both sides of the slide block, a cutting device being mounted on the slide block, and proximity switches cooperating with the limiting blocks being mounted on both sides of the cutting device; it also includes an auxiliary guiding mechanism, the auxiliary guiding mechanism including two roller assemblies, the two roller assemblies being disposed on the upper and lower sides of the transverse slide rail, each roller assembly including two rollers and a guide rope wound between the two rollers, with the adjacent portions of the two guide ropes serving as guiding portions, the two rollers in each roller assembly being rotatably mounted at both ends of the crossbeam, the upper sides of the two limiting blocks being inserted into the corresponding guiding portions, and the lower sides of the two limiting blocks being inserted into the corresponding cooperating portions.

[0008] The portions of the two guide ropes that are opposite to each other are the mating portions, and each of the two mating portions is equipped with an adjustment structure for adjusting the tension of the guide ropes.

[0009] Both adjustment structures include cams, which are rotatably mounted on the front side of the crossbeam, and the circumferential surfaces of the two cams abut against the corresponding mating parts.

[0010] The two cams are respectively mounted on the front side of the crossbeam via adjusting shafts, and the front ends of the two adjusting shafts protrude from the front side of the corresponding cams.

[0011] The two adjustment structures also include adjustment handles, which are respectively sleeved on the front end of the corresponding adjustment shaft.

[0012] Both adjustment structures include an adjustment rotating wheel, an adjustment mating wheel, and an adjustment connecting rod. The two adjustment rotating wheels are rotatably mounted on the front side of the crossbeam. The first ends of the two adjustment connecting rods are fixedly mounted on the corresponding adjustment rotating wheels, and the second ends of the two adjustment connecting rods are fixedly mounted on the corresponding adjustment mating wheels. The circumferential surfaces of the two adjustment mating wheels abut against the corresponding mating parts.

[0013] The two adjusting wheels are respectively provided with annular grooves on their circumferential surfaces.

[0014] The two adjusting rotating wheels are respectively mounted on the front side of the crossbeam via adjusting shafts, and the front ends of the two adjusting shafts protrude from the front side of the adjusting rotating wheels.

[0015] The two adjustment structures also include adjustment handles, which are respectively sleeved on the front end of the corresponding adjustment shaft.

[0016] By adopting the above structure, this utility model has the following beneficial effects:

[0017] 1. This utility model adopts an auxiliary guiding mechanism. Each limit block is inserted on both sides of the corresponding guide rope outside the guide part. In this way, when adjusting the position of each limit block, each limit block slides along the transverse slide rail and the cooperating part of the two guide ropes, so that the limit block slides smoothly without deviation, thereby adjusting to the required position more accurately. Moreover, the position adjustment of the limit block is simple, convenient and time-saving. In addition, the limit block is not an electronic switch, and it is not easy to be damaged by manual pushing.

[0018] 2. This utility model adopts an adjustment structure. When the guide rope deforms and affects the sliding adjustment of the limit block, the corresponding adjustment shaft is rotated to move the matching part of the guide rope toward the direction of the transverse guide rail, so that the guide rope is always in a taut state, ensuring the sliding and guiding function of the limit block on the two guide ropes.

[0025] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0026] Example 1

[0027] A bridge cutter crossbeam with an auxiliary guiding mechanism is an improvement on the crossbeam in a conventional bridge cutter.

[0028] like Figure 1As shown, the conventional crossbeam structure includes a crossbeam 1a, a transverse slide rail 2a, a slide block (not shown in the figure), and two limiting blocks 3a. The crossbeam 1a is arranged transversely. The slide block and the two limiting blocks 3a are slidably engaged with the transverse slide rail 2a. A cutting device is installed on the slide block. The two limiting blocks 3a are conventionally installed on both sides of the cutting device. Proximity switches are installed on both sides of the cutting device. The cutting device is a common cutting device used in bridge cutting machines on the market. The two proximity switches are arranged back to back and are fixedly installed on the housing of the cutting device. The two proximity switches are paired with the two limiting blocks one-to-one. When the cutting device moves, one of the proximity switches moves with the cutting device toward the corresponding limiting block until the proximity switch and the limiting block come into contact and the cutting device stops moving.

[0029] For ease of description, the normal operating state of the bridge cutting machine is taken as the reference state of this utility model. The horizontal direction perpendicular to the transverse direction is the longitudinal direction. In this embodiment, the transverse direction is the left-right direction, the longitudinal direction is the front-back direction, and the position of the slide is the front side, and the opposite side is the rear side.

[0030] like Figure 1 As shown and as Figure 3 As shown, the improvement of this utility model lies in that the crossbeam structure includes an auxiliary guiding mechanism, which is used to assist the two limiting blocks 3a in sliding laterally. The auxiliary guiding mechanism includes two roller assemblies, both of which are located on the front side of the crossbeam 1a, and are respectively disposed on the upper and lower sides of the transverse slide rail 2a. The two roller assemblies have the same structure, so the roller assembly located on the upper side is used as an example for description. The roller assembly includes two rollers 1 and a guide rope 2, and the two rollers 1 are respectively rotatably mounted on the crossbeam 1a. At the left and right ends, the axes of the two rollers 1 are arranged in the front-back direction. The guide rope 2 is wound between the two rollers 1. The guide rope 2 forms a guide portion 21 and a mating portion 22 between the two rollers 1 respectively. The guide portion 21 is closer to the aforementioned transverse slide rail 2a than the mating portion 22, that is, the two guide portions 21 are close to each other. The upper sides of the two limiting blocks 3a are respectively inserted into the upper guide portion 21, and the lower sides of the two limiting blocks 3a are respectively inserted into the lower guide portion 21.

[0031] Furthermore, the rotation structure of the roller assembly described above adopts a conventional installation structure. For example, a rotating shaft is installed on the roller 1, with the rear end of the rotating shaft protruding from the rear end face of the roller 1. Then, a bearing is installed on the crossbeam 1a, and the rear end of the rotating shaft is inserted into the bearing so that the rotating shaft rotates and drives the roller 1 to rotate.

[0032] Furthermore, the aforementioned crossbeam 1a is equipped with adjustment structures at positions corresponding to the two adjacent mating parts 22, for adjusting the tension of the corresponding guide ropes 2. The specific adjustment structures are as follows.

[0033] Since the two adjustment structures are identical, the adjustment structure located on the upper side of the transverse guide rail 2a will be used as an example for explanation. This adjustment structure includes a cam 3, which is rotatably mounted on the front side of the crossbeam 1a. This mounting structure is a conventional structure, for example, a bearing is mounted on the front side of the crossbeam 1a. The center of the cam 3 has a mounting hole, and an adjustment shaft 5 is installed in the mounting hole. The mounting hole of the cam 3 and the adjustment shaft 5 are installed together in a conventional manner, such as by key connection or tight insertion fit. The two ends of the adjustment shaft 5 protrude from the front end face and the rear end face of the mounting hole, respectively, and the rear end of the adjustment shaft 5 is inserted into the bearing. Furthermore, the circumferential surface of the cam 3 abuts against the corresponding mating part 22. Preferably, the cam 3 is located in the middle position of the guide rope 2. In this embodiment, the cam 3 mentioned above is a cam that can be directly purchased on the market.

[0034] Furthermore, in this embodiment, the initial state of the cam 3 is that the outer peripheral surface of the cam 3 is pressed tightly against the mating part 22 relative to the axis closest to the mounting hole, so that when the cam 3 rotates, the mating part 22 will continue to press towards the transverse guide rail 2a, thereby keeping the guide rope 2 taut.

[0035] Furthermore, the aforementioned adjustment structure also includes an adjustment handle 4, which is used to cooperate with the adjustment shaft to drive the cam 3 to rotate, thereby adjusting the tension of the guide rope 2. There are various cooperation structures between the adjustment handle 4 and the adjustment shaft 5, and the cooperation structures of the two are described in detail below.

[0036] The first type of mating structure between the adjusting handle 4 and the adjusting shaft 5 is as follows: the adjusting handle 4 includes an adjusting cylinder 431 and a handle integrally connected to the adjusting cylinder 431. The adjusting cylinder 431 has a lower port. The adjusting handle 4 is snapped onto the front end of the adjusting shaft 5 through the adjusting cylinder 431. The front end of the adjusting shaft 5 protrudes out of the mounting hole of the corresponding cam 3. The inner sidewall of the adjusting cylinder 431 is provided with several protrusions along the circumference. Each protrusion is evenly spaced and arranged along the axial direction of the adjusting cylinder 431. The part between two adjacent protrusions forms a groove. The part of the adjusting shaft 5 protruding out of the mounting hole is provided with a snap-fit ​​block corresponding to each groove. In use, the adjusting cylinder 431 is sleeved on the front end of the adjusting shaft 5. At this time, each snap-fit ​​block is located in the corresponding groove. Then, the handle is rotated to drive the adjusting shaft 5 to rotate, thereby driving the cam 3 to rotate.

[0037] The second type of mating structure between the adjustment handle 4 and the adjustment shaft 5 is that the front end of the adjustment shaft 5 protrudes outside the mounting hole of the cam 3. In this embodiment, the adjustment handle 4 is a conventional box ratchet wrench or socket ratchet wrench. In this way, the adjustment handle 4 is sleeved on the adjustment shaft 5, and the adjustment shaft 5 is rotated by rotating the adjustment handle 4.

[0038] The third type of mating structure between the aforementioned adjusting handle 4 and adjusting shaft 5 can also be that the adjusting shaft 5 is a hollow structure, and the structure of the adjusting shaft 5 is the same as that of the adjusting shaft 5 in the first installation structure. The adjusting cylinder 431 is inserted into the corresponding groove through each protrusion and into the front end of the adjusting shaft 5.

[0039] It should be noted that the adjustment handle 4 and the adjustment shaft 5 can also be detachably connected in other conventional ways, and are not limited to those mentioned above.

[0040] The specific adjustment process of the above-mentioned adjustment structure is as follows: First, the adjustment handle 4 is sleeved on the outside of the adjustment shaft 5, and then the adjustment handle 4 is rotated to drive the adjustment shaft 5 to rotate, thereby causing the cam 3 to rotate. The rotation of the cam 3 causes the cam 3 to gradually move away from the circumference of its mounting hole and continuously move the mating part 22 of the guide rope 2 toward the transverse guide rail 2a, thereby keeping the guide rope 2 in a taut state.

[0041] Example 2

[0042] like Figure 2 As shown and as Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that the structures of the two adjustment structures are different, as detailed below.

[0043] Since the two adjustment structures are identical, the upper adjustment structure will be used as an example for explanation. This adjustment structure includes an adjustment rotating wheel 61, an adjustment mating wheel 62, and an adjustment connecting rod 63. The adjustment rotating wheel 61 is rotatably mounted on the front side of the crossbeam 1a. The adjustment rotating wheel 61 is mounted on the crossbeam 1a using a conventional mounting structure. For example, the adjustment rotating wheel 61 has a mounting hole in the middle, and the adjustment shaft 5 is tightly inserted into the corresponding mounting hole. Then, the two ends of the adjustment shaft 5 protrude from the front and rear sides of the adjustment rotating wheel 61, respectively. A bearing is mounted on the front side of the crossbeam 1a, and the rear end of the adjustment shaft 5 is mounted in the bearing so that the adjustment shaft 5 drives the adjustment rotating wheel 61 to rotate. The first end of the adjustment connecting rod 63 is fixedly mounted on the adjustment rotating wheel 61, and the second end of the adjustment connecting rod 63 is fixedly mounted on the adjustment mating wheel 62. Furthermore, the outer circumferential surface of the adjustment mating wheel 62 abuts against the corresponding mating part 22.

[0044] In a preferred embodiment, the aforementioned adjusting rod 63 has a square rod-shaped structure. A through hole is provided at the first end of the adjusting rod 63 corresponding to the position of the adjusting shaft 5. The first end of the adjusting rod 63 passes through the adjusting shaft 5 via the through hole. The diameter of the through hole is sufficient not to obstruct the rotation of the adjusting shaft 5. Bolts are installed on both sides of the adjusting rod 63 corresponding to the through hole. That is, at least two threaded holes are provided on the adjusting rotating wheel 61 corresponding to the position adjacent to the through hole. In this embodiment, two threaded holes are used as an example. The two threaded holes are arranged opposite to each other. A through hole is provided at the first end of the adjusting rod 63 corresponding to each of the two threaded holes. A bolt 611 is provided between each pair of corresponding through holes and threaded holes. Thus, by screwing the bolts into the through holes and threaded holes in sequence, the first end of the adjusting rod 63 is installed. On the adjusting rotating wheel 61, the second end of the adjusting connecting rod 63 is recessed towards the first end of the adjusting mating wheel 62 to form a mounting recess 631. In other words, the adjusting connecting rod 63 has two mounting lugs formed through the mounting recess 631. The adjusting mating wheel 62 is located inside the mounting recess 631, and the second end of the adjusting connecting rod 63 extends to the middle position of the adjusting mating wheel 62. Through holes are respectively opened on the two mounting lugs, and threaded holes are respectively opened on the adjusting mating wheel 62 corresponding to the two through holes. Bolts 611 are respectively provided for each pair of corresponding through holes and threaded holes. In this way, by screwing the bolts into the through holes and threaded holes in sequence, the second end of the adjusting connecting rod 63 is installed on the adjusting mating wheel 62, thereby realizing the installation of the adjusting connecting rod 63 and ensuring the structural stability of the adjusting structure.

[0045] Furthermore, the outer circumferential surface of the aforementioned adjusting wheel 62 is provided with an annular groove 621, which is used for the mating part 22 on the guide rope 2 to abut against it, so that it is confined within the annular groove 621.

[0046] The specific adjustment process of the above-mentioned adjustment structure is as follows: First, the adjustment handle 4 is sleeved on the outside of the adjustment shaft 5, and then the adjustment handle 4 is rotated to drive the adjustment shaft 5 to rotate, thereby causing the adjustment rotating wheel 61 to rotate. The rotation of the adjustment rotating wheel 61 drives the adjustment connecting rod 62 to rotate, and then drives the adjustment mating wheel 62 to make a circular motion around the axis of the adjustment rotating wheel 61 as the base point, so that the mating part 22 of the guide rope 2 continues to move along the transverse guide rail 2a until the guide rope 2 is in a taut state.

[0047] This utility model discloses a bridge cutting machine crossbeam with an auxiliary guiding mechanism. The specific working process is as follows: When adjusting the position of the limiting block 3a on the crossbeam 1a, an external force is used to push the limiting block 3a to move. Since the limiting block 3a is slidably mounted on the transverse guide rail 2a, and its upper and lower sides are respectively sleeved on the corresponding guide ropes 2, the operator can easily push the limiting block 3a along the transverse guide rail 2a. The cooperating part 22 of the guide rope 2 guides the limiting block 3a, allowing it to slide smoothly, quickly, and effortlessly. Furthermore, when the limiting block 3a is frequently used and the corresponding guide rope 2 is prone to loosening, the operator can insert the adjusting handle 4 into the front end of the adjusting shaft 5 and then rotate the adjusting handle 4 to adjust the downward movement of the cooperating part 22 of the guide rope 2 along the transverse guide rail 2a, thus keeping the guide rope 2 taut. The operation is simple, convenient, and saves time and effort.

[0048] The above description is only a preferred embodiment of this invention. All equivalent changes and modifications made within the scope of the claims of this utility model shall fall within the scope of the claims of this utility model.
