Description

Technical Field

[0001] The present invention relates to the technical field of traction machines, and in particular to a rope pulley and housing integrated traction machine. Background Art

[0002] Traction machines are classified into two types according to their appearance: thin gearless traction machines and geared traction machines.

[0003] The thin traction machine is to fasten the traction wheel directly to the output shaft of the driving host, and the power is directly output. In order to make the traction movement stable, higher requirements are placed on the driving host. And the motor power is directly output, which is only suitable for light load scenarios.

[0004] The gear type traction machine is equipped with a gearbox. The output shaft of the driving main machine is connected to the input shaft of the gearbox. The traction wheel is fastened to the output shaft of the gearbox. The gearbox is used for transition to convert the high-speed rotational motion of the driving main machine into a suitable speed and torque. The rotational speed and torque can be adjusted through the combination of gears. It can not only amplify the torque, but also is safer to use than direct power output.

[0005] However, the gear-type traction machine has a larger appearance due to the addition of a gearbox, which increases the demand for installation space; and its large size makes it inconvenient to carry and hoist.

[0006] In addition, the braking of traditional traction machines is mostly achieved by driving the holding brake to close and compressing the brake disc. In heavy loads, only friction is used for braking. After a certain period of use, if the brake disc and other related equipment are not replaced in time, it is easy to produce a smooth surface and slip, thus affecting the braking effect.

[0007] To this end, the present invention provides a rope pulley housing integrated traction machine to solve the safety problems of gear-type traction machines that are large in size and difficult to install and carry, and the clamping friction braking method that is prone to slipping and crashing when overloaded.

[0050] The top of the two brake arms 14 are integrally provided with a second insert tube 16, and a brake rod 18 is inserted through the two insert tubes 16. The brake rod 18 is a threaded shaft, and a plurality of self-locking nuts 2 are screwed on both sides of the insert tube 16 on the brake rod 18, and the self-locking nuts 2 on both sides are respectively against the two sides of the insert tube 16, so as to connect the brake rod 18 with the brake arm 14.

A limit plate is inserted into the stud, and the limit plate abuts against the connecting diameter change between the stud and the movable pull rod 19. A plurality of self-locking nuts 1 are screwed on the stud, and the self-locking nuts abut against the limit plate to brake the limit plate. A spring 28 is sleeved on the movable pull rod 19 between the limit plate and the insert sleeve 17, and the spring 28 is always in a compressed state. Screw sleeves are provided on both sides of the mounting seat 13, and the movable pull rod 19 is provided with threads on the side facing the mounting seat 13 and is screwed and installed in the screw sleeve to achieve the connection between the movable pull rod 19 and the mounting seat 13.

[0052] The bent parts of the two brake arms 14 are provided with straight slot holes 24, and left and right mounting shafts 25 are slidably installed in the two straight slot holes 24 along the length direction of the straight slot holes 24. Limiting blocks 26 are provided in the two straight slot holes 24 on the opposite sides of the two mounting shafts 25, and a spring 27 is provided in the straight slot holes 24 between the opposite ends of the two mounting shafts 25 and the mounting shafts 25, and the spring 27 is always in a compressed state.

[0054] 5. Heat dissipation component, used for internal heat dissipation of the planetary reduction mechanism.

[0055] In this embodiment, an L-shaped pressure rod 22 is fastened and installed on the mounting seat 13 via a fastener, and two groups of pressure rods 22 are provided, symmetrically arranged on both sides of the horizontal center line of the traction wheel 12.

[0056] In this embodiment, the spacing between the inner wall of the second insert cylinder 16 and the outer wall of the movable rod 19, and the universal joint 20 between the brake rod 18 and the output end of the dual-drive brake magnet 21 are all for adjusting the movable spacing when the brake arm 14 is deflected. Alternatively, a vertical slot is provided through the side wall of the brake arm 14, and the ends of the movable rod 19 and the brake rod 18 are both fastened with a U-shaped frame, and the ends of the two arms of the U-shaped frame are fastened with a coupling, which is inserted into the vertical slot to achieve the connection between the movable rod 19, the brake rod 18 and the brake arm 14, and the connection between the ends of the movable rod 19 and the brake rod 18 can move on the brake arm, so that the connection between the movable part brake arm 14 and the output end of the fixed part dual-drive brake magnet 21 can be achieved without interfering with the movement.

[0057] In this embodiment, by controlling the length of the movable pull rod 19 screwed into the threaded sleeve, the compressed distance of the spring 27 can be adjusted, thereby adjusting the pressure applied to the brake arm 14, and then adjusting the clamping friction force of the brake shoe 15 on the brake disc 23.

[0058] In this embodiment, the outer diameter of the second sun gear 11 is larger than the outer diameter of the first sun gear 7 to avoid interference with the installation of the traction sheave 12.

[0059] In this embodiment, the shaft diameters (modules) of the first planetary gear 6, the output gear 8, the input gear 9, and the second planetary gear 39 are gradually increased, thereby implementing a step-by-step increase in the transmission ratio and the minimum transmission ratio is also greater than 1, thereby achieving the transmission speed reduction effect of the planetary reduction mechanism.

[0060] In this embodiment, refer to the attached Fig.18 As shown, the first planet carrier 5 and the second planet carrier 10 each include two face plates, which are connected by welding of triangle irons. The planetary gears are dispersed between two adjacent triangle irons. The outer edge of the planetary gear is exposed outside the face plate and meshes with the sun gear. The planetary carrier with such a structure can provide a good installation foundation for both ends of the output wheel 8 and the input wheel 9, making the installation more stable.

[0061] In this embodiment, the first planetary gear 6 , the output gear 8 , the second planetary gear 39 , and the input gear 9 are all external gears, and the first sun gear 7 and the second sun gear 11 are all internal gears.

[0062] In this embodiment, when the V-shaped rod 37 deflects, it drives the inserting frame 29 to vertically insert into the brake block 30, so that the inserting frame 29 is vertically connected to the connecting line of the two brake blocks 30, so as to prevent the inserting frame 29 from being biased relative to the inclined surface due to force.

[0063] In this embodiment, the inner wall of the brake shoe 15 is fastened with a friction plate by countersunk screws, so that the friction plate can be replaced to always maintain effective friction braking.

[0064] In this embodiment, the end of the inserting frame 29 is an arc-shaped protrusion. After the brake block 30 abuts against the inserting frame 29, the protrusion can play a certain role in preventing it from falling off.

[0065] Principle details of this embodiment: When in use, the driving main unit 2 drives the sleeve 4 to rotate through the cooperation between the spline and the spline groove, and the sleeve 4 drives the first planetary carrier 5 to rotate, and the first planetary carrier 5 drives all the first planetary gears 6 to perform a circular motion. In the process of the circular motion, the first planetary gear 6 rotates due to meshing with the first sun gear 7, and all the first planetary gears 6 mesh with the output gear 8 to drive the output gear 8 to rotate. The output gear 8 drives the coaxially arranged input gear 9 to rotate. The input gear 9 drives all the second planetary gears 39 to rotate, and all the second planetary gears 39 jointly drive the second sun gear 11 to rotate, and the second sun gear 11 drives the traction wheel 12 to rotate, thereby realizing the winding or extension of the traction rope.

[0066] In the above process, the first planetary gear 6 and the output wheel 8, and the input wheel 9 and the output wheel 8 are all deceleration movements, thereby reducing the input speed of the driving main machine 2. At the same time, the torque is amplified by utilizing the coordination between the gears, thereby reducing the output load requirement of the driving main machine 2 and realizing high torque output of a small power motor.

[0067] The planetary reduction mechanism in this scheme has been improved on the basis of the traditional planetary reduction mechanism. The final output of the traditional planetary reduction mechanism is the gear meshing in the planetary gear as the output shaft. In this scheme, a two-stage planetary mechanism is adopted, and the rotation of the second sun gear 11 is used as the final output end. Compared with the power transmission of a single set of gears, the two-stage planetary structure not only realizes the torque diversion, reduces the load borne by a single gear and reduces wear, but also can further expand the torque increase effect of the planetary structure; and the second sun gear 11 is used as the output source, and the outer edge width of the second sun gear 11 is greater than half of the axial length of the traction wheel 12, thereby increasing the force pulling area of ​​the traction wheel 12 and improving the rotation stability of the traction wheel 12. And the traction wheel 12 is set outside the planetary reduction mechanism, which can amplify the axial length of the traction wheel 12, extend the length of the winding groove, and then increase the traction length; and realize the hidden design of the planetary reduction mechanism, thereby reducing the external volume of the entire equipment, thereby facilitating installation and transportation.

[0068] When the traction wheel 12 stops, no current flows through the coil in the dual-drive brake magnet 21. At this time, there is no attraction between the electromagnet cores. The brake arm 14 approaches the brake disc 23 under the action of the spring 27, so that the brake shoe 15 holds the brake disc 23 tightly, and the first-level braking is achieved through the compression friction. In this process, the brake shoe 15 first contacts the brake disc 23. As the brake arm 14 continues to deflect, the mounting seat 13 slides in the straight slot hole 24 and squeezes the spring 27 until it abuts against the limit block 26, and the spring 27 is compressed. During the sliding process of the mounting shaft 25, the V-shaped rod 37 deflects, and the V-shaped rod 37 drives the bracket 29 to be inserted between the brake blocks 30 on the brake disc 23. The second-level braking of the brake disc 23 is achieved by plugging the bracket 29 between the brake blocks 30. Compared with the compression friction braking alone, this plug-in braking method is more stable.

[0069] In this embodiment, a speed sensor is provided in the base 3 at the position corresponding to the shaft sleeve 4, which is used to monitor the output state of the drive host 2. The acceleration sensor and the control box of the drive motor are electrically connected to the control box of the dual-drive brake magnet 21. When the drive host 2 stops rotating, the shaft sleeve 4 stops, thereby giving a signal to the dual-drive brake magnet 21 to brake, and brakes when stationary. Before traction is required, before the drive host 2 rotates, the dual-drive brake magnet 21 stops braking. After the brake is turned off, the drive host 2 starts to traction to avoid motion interference.

[0070] Embodiment 2: In a conventional planetary structure, the planetary gear performs an epicyclic motion, such as the first planetary gear 6 in this embodiment. When the main engine 2 is driven to open and close, especially when it is started, the first planetary gear 6 in an epicyclic motion will be impacted at the moment of the epicyclic motion, thereby causing the first planetary gear 6 to wear more severely and shorten its service life. Therefore, in this embodiment, a different structure of the first planetary gear 6 is provided: The first planetary gear 6 includes a gear body 31 , a plurality of inner gear pieces 32 , and a plurality of outer gear pieces 33 .

[0071] The gear body 31 is rotatably mounted at the axis of the first planet carrier 5, and a plurality of inner teeth 32 and outer teeth 33 are arranged alternately, and a spacer 34 is arranged between each adjacent inner teeth 32 and outer teeth 33, and a spacer 34 is arranged on the outer sides of both ends of the combination of the inner teeth 32 and the outer teeth 33. The hub of the gear body 31 is clamped with a blocking cover 45 at both ends, and the blocking cover 45 is buckled on the outermost spacer 34. The outer edge surfaces of the shaft ends on both sides of the gear body 31 are provided with a clamping groove, and a retaining spring is embedded in the clamping groove, and the retaining cover 45 is limited by the retaining spring against the blocking cover 45. The outer teeth 33 and the inner teeth 32 are made of high-strength and high-toughness metals, such as ultra-high-strength steel and deformation distribution steel (D&P steel).

[0072] When in use, the gear body 31 is wrapped by the inner tooth piece 32 and the outer tooth piece 33 to eliminate the tooth gap, and the inner tooth piece 32 and the outer tooth piece 33 are used to withstand the impact load, thereby reducing the damage caused by the instantaneous impact. Moreover, the wrapping body composed of a plurality of inner tooth pieces 32 and outer tooth pieces 33 can be replaced individually even if it is damaged, which is lower than the overall scrapping after damage, and the cost of repair and replacement is lower.

[0073] In this embodiment, a plurality of latches penetrating all the inner tooth pieces 32, the outer tooth pieces 33, and the spacers 34 are commonly inserted between the two shields 45. The latches are used to position the inner tooth pieces 32 and the outer tooth pieces 33 to ensure the tightness of the connection of the inclusion formed by the inner tooth pieces 32 and the outer tooth pieces 33 to prevent mutual misalignment during transmission, and at the same time, the transmission torque of the outer tooth pieces 33 and the inner tooth pieces 32 is transmitted through the latches.

[0074] Embodiment 3, in this solution, in order to reduce the additional wear on the tooth surface caused by dust in the external environment during operation, in this solution, sealing measures are provided at the connection parts between the base 3 and the first sun gear 7, the first sun gear 7 and the second planetary carrier 10, and the second sun gear 11 and the second planetary carrier 10. For example, a sealing gasket is provided at the connection parts between the base 3 and the first sun gear 7, the first sun gear 7 and the second planetary carrier 10, and a sealing ring is provided between the second sun gear 11 and the second planetary carrier 10. Shaft seals are provided outside the rotating bearings of all rotating parts. To form a sealed environment. At the same time, it can also prevent the lubricating oil on components such as bearings from leaking inside the equipment.

[0075] Embodiment 4, in this scheme, the heat dissipation assembly includes a wheel sleeve 40 rotatably mounted on the base 3, and the outer wall of the wheel sleeve 40 has a plurality of spiral blades 41 in an annular array. The base 3 is provided with a plurality of air inlet holes 35 in the area inside the first sun gear 7, and the second planetary carrier 10 is provided with a plurality of air outlet holes 36 on the side away from the base 3, and the air inlet holes 35 and the air outlet holes 36 are provided with filter screens. The outer edge surface of the rotating shaft of the first planetary carrier 5 facing the base 3 is provided with a plurality of expansion holes 44 arranged along the radial direction of the rotating shaft, and a sealing plug is slidably installed in the expansion hole 44, and a hot expansion gas, such as nitrogen, is provided in the expansion hole 44 in the space isolated by the sealing plug. The sealing plug is provided with an insert block 43, and the inner wall of the wheel sleeve 40 is provided with an insert hole 42 corresponding to the insert block 43.

[0076] According to the above technical solution: When the temperature is not high, hot air is dissipated through the air inlet 35 and the air outlet 36 to dissipate heat spontaneously.

[0077] After the internal temperature gradually rises to a certain value, the hot expansion gas in the expansion hole 44 continues to expand, thereby pushing the sealing plug outward, and the sealing plug drives the plug block 43 to move outward until the plug block 43 can be inserted into the plug hole 42, so that the sleeve 4 is connected to the wheel sleeve 40, and then drives the spiral blades 41 to rotate, forming active wind force, accelerating the flow of hot air, and thus improving the heat dissipation effect. And from the above embodiment, it can be seen that the input end of the planetary reduction mechanism has the fastest speed, that is, the sleeve 4 directly connected to the drive host 2 has the fastest speed, then the speed of the spiral blades 41 matched with the sleeve 4 is the fastest speed in this device.
