Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a counting device applied to a winch, a winch mechanism and a lifting device. Background Art

[0002] In the related technology, at present, the winch height counting of crawler crane tamping machine is the key technology for free hook drop movement and subsequent installation of unmanned tamping intelligent system. However, the winch counting currently used is the proximity switch method, which has the problem of missing teeth in many cases, resulting in low accuracy. Moreover, since the sensing distance between the proximity switch and the winch teeth is about 2-3mm, in the case of the above close distance, if the drum is adhered to foreign objects, the proximity switch will be easily damaged, resulting in inaccurate counting, excessively long rope output, and damage to nearby parts and components by the wire rope. When the proximity switch is too far from the drum, it will lead to the failure of detecting excessively long rope output. In addition, since the proximity switch has a temperature resistance of only 70 degrees and no protective device is set, when the winch temperature is high in summer, it will cause the proximity switch temperature to be high, which will lead to inaccurate counting and reduced accuracy. Therefore, there is an urgent need for a new and reliable tamping machine winch height counting device to solve this problem. Utility Model Content

[0008] According to an embodiment of the present utility model, the first linkage member is a first gear member in the shape of a gear, the second linkage member is a second gear member in the shape of a gear, and the linkage shaft is a gear shaft;

[0009] The first gear member is meshed with the second gear member, and the gear shaft is connected to the encoder.

[0010] According to an embodiment of the present utility model, the first gear member is a gear ring, and the flanges on both sides of the upper drum of the hoisting mechanism form the gear ring.

[0011] According to an embodiment of the utility model, the transmission assembly further comprises a mounting seat, the mounting seat is provided with a mounting hole, the encoder passes through and is fixed in the mounting hole, and the mounting seat is fixedly mounted on a side of the hoisting mechanism adjacent to the gear ring.

[0012] According to an embodiment of the present invention, the encoder is connected to the gear shaft via a coupling.

[0013] According to one embodiment of the utility model, the transmission assembly also includes a rolling bearing, which is located between the second gear member and the mounting seat and is sleeved on the outer side of the gear shaft. A bearing seat is also sleeved on the outer side of the rolling bearing, and the bearing seat is fixedly connected to the mounting seat.

[0014] According to an embodiment of the utility model, a bearing space for installing the rolling bearing is formed between the bearing seat and the gear shaft, and two bearing end covers are respectively provided at both ends of the bearing space.

[0015] According to an embodiment of the utility model, a sealing ring is provided between the bearing end cover and the bearing seat.

[0016] The hoisting mechanism according to the embodiment of the second aspect of the utility model comprises: the counting device applied to the hoisting as described in the embodiment of the first aspect of the utility model;

[0017] It also includes a reel and a hoisting body, wherein the reel is rotatably mounted on the hoisting body, the first gear member is fixedly mounted on the reel of the hoisting mechanism, and the encoder is fixedly mounted on the hoisting body.

[0018] According to an embodiment of the utility model, the first gear member is a gear ring, and the end of the drum is provided with a plurality of mounting grooves in sequence along its outer circumference, and the gear ring is fixedly installed around the outer circumference of the drum through the plurality of mounting grooves.

The utility model provides a counting device applied to the hoisting, which has the following advantages compared with related counting devices:

[0020] (1) Higher accuracy: This solution uses an encoder as a winch height counting device. Compared with the proximity switch method, the encoder can provide higher accuracy. Because the proximity switch often loses teeth, the counting is inaccurate. The encoder can more accurately calculate the length of the wire rope by measuring the rotation angle, thereby improving the measurement accuracy of the lifting height.

[0021] (2) Stronger anti-interference ability: The sensing distance between the proximity switch and the winch gear is relatively close, and it is easily affected by foreign matter sticking to the drum, causing damage to the proximity switch. However, the encoder in this solution is installed in a relatively independent position, is not easily affected by foreign matter, and has a strong anti-interference ability.

[0022] (3) Better high temperature resistance: The encoder in this solution has high temperature resistance and can work normally in high temperature environment. In contrast, the proximity switch has poor temperature resistance, which can easily lead to inaccurate counting and reduced accuracy when the winch temperature is high in summer.

[0023] (4) Higher safety: Since this solution uses an encoder to count the height, the height of the lifting object can be known in real time, which helps to improve the safety of the lifting operation. The proximity switch method may fail when it detects that the rope is too long, causing the wire rope to damage nearby parts, increasing safety hazards.

[0024] (5) More suitable for intelligent systems: The encoder in this solution outputs digital signals, which is convenient for integration with subsequent human-free intelligent systems. The signal output by the proximity switch is relatively simple and may require additional processing to be compatible with the intelligent system.

[0025] In summary, the counting device proposed in the utility model has obvious advantages over the solutions in related technologies in terms of accuracy, anti-interference ability, high temperature resistance, safety and intelligent system compatibility, and can better meet the needs of counting the winch height of crawler cranes and ramming machines.

[0036] 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.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0038] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0039] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0040] The following describes a counting device and a hoisting mechanism applied to a winch provided by the utility model with reference to the accompanying drawings. It should be pointed out that the hoisting mechanism provided in the embodiment of the second aspect of the utility model includes the counting device applied to the winch provided in the embodiment of the first aspect of the utility model.

[0041] like Figures 1 to 6 As shown, the counting device applied to the winch according to the embodiment of the first aspect of the utility model includes a first linkage member, an encoder 13 and a transmission assembly.

[0042] The first linkage member is directly or indirectly mounted on the drum 7 of the hoisting mechanism, and the first linkage member can rotate along with the rotation of the drum 7 .

[0043] The first linkage is in transmission connection with the encoder 13 through the transmission assembly, and the encoder 13 calculates the number of rotations of the first linkage through the transmission assembly. The transmission assembly includes a fixedly connected second linkage and a linkage shaft, the first linkage is in transmission connection with the second linkage, and the linkage shaft is connected to the encoder 13.

[0044] It can be understood that since the wire rope is wound around the outside of the drum in an orderly manner, one end of the wire rope can be detachably fixed on the winch, and the other end is connected to the hook through the arm head of the rammer. Therefore, by obtaining the number of rotations or rotation angles of the drum, the length of the wire rope retracted and released by the winch mechanism can be calculated.

[0045] As for the counting device of the utility model, when the drum rotates, the first linkage rotates with the drum, and the first linkage transmits the rotational motion to the second linkage, that is, the second linkage rotates with the rotation of the first linkage, and the linkage shaft also rotates with the rotation of the second linkage, and then the encoder 13 records the number of rotations of the linkage shaft. At this time, the data recorded by the encoder 13 can be used to deduce the number of rotations or rotation angles of the drum, so the length of the retracted wire rope of the hoisting mechanism can be further calculated. In this way, the counting device of the utility model can monitor the retracted and released length of the wire rope in real time when the winding mechanism realizes the hoisting function, thereby realizing the monitoring of the lifting height of the goods.

[0046] According to some embodiments of the utility model, the first linkage member, the second linkage member and the linkage shaft can be a gear transmission structure. In this case, the first linkage member and the second linkage member are both gear members; or, the first linkage member, the second linkage member and the linkage shaft can also be other forms of transmission structures. The utility model does not impose any special restrictions on this, as long as the above-mentioned transmission structure can transmit the movement of the reel to the encoder 13.

[0047] For ease of description, the following description will take the example that both the first linkage member and the second linkage member are gear members, that is: the first linkage member is a gear-shaped first gear member 8, the second linkage member is a gear-shaped second gear member 1, and the linkage shaft is the gear shaft 3, the first gear member 8 is meshed with the second gear member 1, and the gear shaft 3 is connected to the encoder 13.

[0048] According to the counting device applied to the hoisting according to the embodiment of the utility model, its specific working principle is as follows: the first gear member 8 is installed on the drum 7 of the hoisting mechanism, and can rotate with the rotation of the drum 7. The function of the first gear member 8 is to transmit the rotational motion of the drum 7 to the encoder 13. Further, the transmission assembly is responsible for connecting the first gear member 8 with the encoder 13, and the transmission of the rotational motion is realized by the meshing transmission relationship between the first gear member 8 and the second gear member 1. The encoder 13 is a sensor for measuring the rotation angle of the first gear member 8. It can be understood that the rotation angle of the first gear member 8 is also the rotation angle of the drum 7, so that the encoder 13 can calculate the length of the wire rope of the hoisting mechanism according to the rotation angle of the drum 7. Among them, the encoder 13 can be an incremental encoder 13 or an absolute encoder 13, depending on the application requirements.

[0049] According to the counting device applied to the hoisting of the embodiment of the utility model, the specific working process is as follows: when the hoisting mechanism retracts and releases the wire rope, the drum 7 will rotate accordingly. The first gear member 8 is installed on the drum 7, so it will also rotate with the rotation of the drum 7. Through the meshing second gear member 1 and the gear shaft 3, the rotational movement of the first gear member 8 is transmitted to the encoder 13. The encoder 13 measures the rotation angle and converts the angle information into a digital signal through a signal processing circuit. These digital signals can be used to calculate the length of the wire rope to achieve height counting, so as to understand the height of the lifting object in real time.

[0050] It should be explained that the height count here refers to the height of the hook of the wire rope from the ground. In the utility model, the length of the wire rope released is calculated by a counting device. Since the height difference between the ground and the boom head is a fixed value, the length of the hook hanging from the boom head can be calculated by the length of the wire rope released, and then the above height can be obtained by subtracting the hanging length from the height difference between the ground and the boom head.

[0051] Encoder 13 Figure 5 and Figure 7 As shown, according to some embodiments of the present invention, the first gear member 8 is a gear ring, which is fixedly mounted on one side of the reel 7 and arranged around the reel 7. Alternatively, in some other embodiments of the present invention, the flange of the reel 7 and the gear ring can also be arranged as an integral structure, that is, the gear ring is formed on the flange of the reel 7 and is integrally formed therewith.

[0052] It can be understood that the ring gear is a gear-shaped part with multiple teeth for meshing with other gears to transmit force and motion. In the hoisting mechanism of the present utility model, the ring gear is fixedly mounted on one side of the drum 7 and arranged around the drum 7. Such a design enables the ring gear to maintain close contact with the drum 7, ensuring that force and rotational motion can be accurately transmitted during the hoisting process.

[0053] Specifically, when the drum 7 rotates, the ring gear will also rotate. The rotation of the ring gear will be transmitted to the encoder 13 through the transmission components (such as the second gear member 1, the coupling, etc.). The encoder 13 will indirectly measure the rotation angle of the ring gear, thereby calculating the retracted and released length of the wire rope on the drum 7. This design enables the counting device to monitor the position of the wire rope in real time and accurately, providing important reference information for the hoisting operation.

[0054] Furthermore, there can be many ways to install the gear ring and the drum 7, such as through keyways, threaded connections or welding, and the present invention does not impose any special restrictions here, as long as the installation method adopted can ensure that the connection between the gear ring and the drum 7 is stable and reliable, and can maintain precise meshing during long-term use.

[0055] like Figure 1As shown, according to some embodiments of the present invention, the transmission assembly further includes a mounting seat 5, which is provided with a mounting hole, the encoder 13 passes through and is fixed in the mounting hole, and the mounting seat 5 is fixedly mounted on a side of the hoisting mechanism adjacent to the gear ring.

[0056] In this embodiment, the main function of the mounting base 5 is to provide support and fixation for the encoder 13, ensuring accurate alignment between the encoder 13 and the first gear member 8 (gear ring), helping to improve the measurement accuracy and stability of the counting device, and providing more reliable support for the hoisting operation.

[0057] The mounting base 5 can be made of metal or other solid materials, which have certain strength and stability. A mounting hole is provided on the mounting base 5, and the mounting hole can be used to pass the encoder 13 through and fix it in the mounting base 5. The size and shape of the mounting hole need to match the encoder 13 to ensure that the encoder 13 can be stably mounted on the mounting base 5.

[0058] Furthermore, in order to keep the encoder 13 at an appropriate distance from the gear ring, the mounting seat 5 is fixedly mounted on one side of the hoisting mechanism adjacent to the gear ring. Such a layout helps to reduce errors in the transmission process and improve the measurement accuracy of the counting device.

[0059] Furthermore, in practical applications, the mounting seat 5 can be fixed on the hoisting mechanism by bolts, welding, etc. Of course, the mounting seat 5 can also be installed on the turntable near the drum, and the utility model does not make special restrictions here. At the same time, the connection between the encoder 13 and the mounting seat 5 can also be adopted in a variety of ways, such as threaded connection, snap connection, etc., to ensure that the encoder 13 can work stably during operation.

[0060] like Figure 6 As shown, according to some embodiments of the present invention, the encoder 13 is connected to the gear shaft 3 via a coupling. In this way, the gear shaft 3 and the encoder 13 can be connected by a coupling, so that the rotation of the gear shaft 3 can be stably transmitted to the encoder 13.

[0061] like Figure 1 As shown, according to some embodiments of the utility model, the transmission assembly also includes a rolling bearing 2, which is located between the second gear member 1 and the mounting seat 5 and is sleeved on the outer side of the gear shaft. A bearing seat 4 is also sleeved on the outer side of the rolling bearing 2, and the bearing seat 4 is fixedly connected to the mounting seat 5.

[0062] In this embodiment, in order to further improve the stability of the transmission assembly and reduce friction, a rolling bearing 2 is added, which is located between the second gear member 1 and the mounting seat 5 and sleeved on the outer side of the gear shaft. The above design helps to support the gear shaft 3 so that it can run smoothly during rotation, reduce friction loss, and improve transmission efficiency.

[0063] In addition, a bearing seat 4 is sleeved on the outer side of the rolling bearing 2, and the function of the bearing seat 4 is to fix and support the rolling bearing 2. The bearing seat 4 is fixedly connected to the mounting seat 5, and can be connected by bolts, welding, etc. This layout makes the transmission assembly more stable, which is conducive to improving the performance of the entire counting device.

[0064] In practical applications, the materials of the rolling bearing 2 and the bearing seat 4 need to have sufficient strength and wear resistance to withstand long-term operation. At the same time, in order to ensure the normal operation of the rolling bearing 2, regular maintenance and lubrication are required.

[0065] In summary, the transmission assembly is added with rolling bearing 2 and bearing seat 4 to improve the stability of the transmission assembly and reduce friction. This design helps to improve the overall performance of the counting device and provide more accurate measurement data for the hoisting operation.

[0066] like Figure 2 As shown, according to some embodiments of the present invention, a bearing space for mounting a rolling bearing 2 is formed between the bearing seat 4 and the gear shaft, and two bearing end covers 10 are respectively provided at both ends of the bearing space.

[0067] It can be understood that in order to further protect the rolling bearing 2 and ensure its normal operation, a bearing space is formed between the bearing seat 4 and the gear shaft. This bearing space is used to install the rolling bearing 2 and provide it with sufficient space for rotation. The design of the bearing space matches the size and type of the rolling bearing 2 to ensure that the bearing can be installed smoothly and work normally.

[0068] Furthermore, in order to protect the rolling bearing 2 in the bearing space, two bearing end covers 10 are respectively provided at both ends of the bearing space. The two end covers can seal the bearing space to prevent dust, dirt and other impurities from entering the bearing space, thereby avoiding damage to the rolling bearing 2. At the same time, the end covers can also prevent lubricant leakage to ensure that the bearing is fully lubricated.

[0069] In some specific embodiments, the two bearing end covers 10 can be fixed to the bearing seat 4 by bolts, buckles, etc., so as to facilitate installation and removal, and the utility model does not make special restrictions here. In practical applications, it is necessary to regularly check the sealing performance of the end covers to ensure that the rolling bearing 2 in the bearing space is well protected.

[0070] like Figure 2 As shown, according to some embodiments of the present utility model, a sealing ring 11 is provided between the bearing end cover 10 and the bearing seat 4 .

[0071] In this embodiment, in order to further improve the sealing performance of the bearing space and reduce the risk of external contaminants entering the bearing space, a sealing ring 11 is provided between the first bearing end cover 10 and the bearing seat 4, and a sealing ring 11 is provided between the second bearing end cover 10 and the bearing seat 4. The two sealing rings 11 together constitute an effective sealing system, further improving the sealing performance of the bearing space, protecting the bearing from the influence of the external environment, and thus improving the reliability and stability of the entire counting device.

[0072] The sealing ring 11 can be made of rubber, polyurethane or other materials with good sealing performance, and the utility model does not make any special restrictions here. The size and shape of the sealing ring 11 need to match the bearing seat 4 and the end cover to ensure that it can be properly installed and play a sealing role.

[0073] In practical applications, it is necessary to regularly check the wear of the seal ring 11 and replace it with a new seal ring 11 if necessary to maintain good sealing performance. At the same time, ensure the use and replenishment of lubricant to maintain the normal operation of the bearing.

[0074] like Figure 3 As shown, according to some embodiments of the present invention, the bearing seat 4 is further provided with an oil supply hole connected to the bearing space, and a grease nipple 12 is installed in the oil supply hole.

[0075] In this embodiment, in order to facilitate the user to lubricate and maintain the rolling bearing 2, an oil supply hole connected to the bearing space is provided on the bearing seat 4. The function of the oil supply hole is to allow the user to conveniently inject lubricating oil into the bearing space, ensure that the rolling bearing 2 works in a good lubricated state, extend its service life, and improve the performance of the entire counting device.

[0076] Furthermore, a grease nipple 12 is installed in the oil supply hole, and the grease nipple 12 can conveniently inject lubricating oil into the bearing space. The user only needs to inject lubricating oil from the grease nipple 12, and the lubricating oil will enter the bearing space through the oil supply hole to lubricate the rolling bearing 2.

[0077] In order to ensure the lubrication effect, the user needs to regularly check the working state of the grease nipple 12, and replace or repair it in time if necessary. At the same time, select the appropriate type and viscosity of lubricating oil to ensure the normal operation of the rolling bearing 2.

[0078] In summary, by providing the oil supply hole and the grease nipple 12 on the bearing seat 4, the user can conveniently perform lubrication and maintenance on the rolling bearing 2 to ensure its normal operation, thereby improving the reliability and service life of the entire counting device.

[0079] like Figure 4As shown, according to some embodiments of the present invention, a shaft end baffle 6 is provided on a side of the second gear member 1 away from the mounting seat 5, and the shaft end baffle 6 is arranged around the gear shaft and is used to prevent the second gear member 1 from separating from the gear shaft.

[0080] In this embodiment, in order to ensure that the second gear member 1 can work stably and avoid accidental falling off, a shaft end baffle 6 is provided on the side of the second gear member 1 away from the mounting seat 5. The shaft end baffle 6 is arranged around the gear shaft to fix and protect the second gear member 1 and prevent it from falling off the gear shaft during use.

[0081] The shaft end baffle 6 can be made of metal or other solid materials with certain strength and wear resistance. The shape and size of the shaft end baffle 6 need to match the second gear member 1 and the gear shaft to ensure that it can be tightly fixed in the corresponding position.

[0082] In this way, by providing the shaft end baffle 6 at the shaft end of the second gear member 1, the stability and safety of the transmission assembly are improved, and the normal operation of the counting device is ensured.

[0083] like Figures 1 to 7 As shown, the hoisting mechanism according to the embodiment of the second aspect of the utility model includes the counting device applied to the hoisting described in the embodiment of the first aspect of the utility model.

[0084] like Figure 7 As shown, the hoisting mechanism further includes a drum 7 and a hoisting body, the drum 7 is rotatably mounted on the hoisting body, the first gear member 8 is fixedly mounted on the drum 7 of the hoisting mechanism, and the encoder 13 is fixedly mounted on the hoisting body.

[0087] For example Figure 5 As shown, find the corresponding installation groove 9 inside the original winch gear ring, and design the gear ring based on the installation groove 9. It should be noted that the counting gear ring dividing line, the bottom of the tooth between the two holes 14 is divided into 5 pieces in total, and the division must ensure that each tooth is complete. Mark the large surface of the gear ring in a clockwise direction, marking 5-1, 5-2, 5-3, 5-4, and 5-5 respectively. Fix the gear ring clockwise, and the gear ring boss and the end face of the gear ring installation groove 9 are completely fitted during installation. During the installation process, install one gear ring first, and then rotate the drum 7 to install the remaining 4 pieces in sequence.
