Description

Technical Field

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

[0002] According to the classification of the appearance, there are two types of traction machines: a thin-type gearless traction machine and a geared traction machine.

[0003] The thin-type traction machine directly fastens and installs the traction wheel on the output shaft of the driving host, and the power is directly output. In order to make the traction movement stable, there are relatively high requirements for the driving host. And the direct output of the motor power is only applicable to light-load scenarios.

[0004] The geared traction machine is provided with a gearbox. The output shaft of the driving host is connected to the input shaft of the gearbox, and the traction wheel is fastened to the output shaft of the gearbox. Through the transition of the gearbox, the high-speed rotational movement of the driving host is converted into appropriate speed and torque, and through the combination of gears, the adjustment of the rotational speed and torque is realized. It can not only amplify the torque, but also be safer to use compared with the direct output of power.

[0005] However, due to the added gearbox, the appearance of the geared traction machine will become correspondingly larger, and the requirement for the installation space will increase; moreover, it has a large size and is not convenient for handling and hoisting.

[0006] In addition, the braking of traditional traction machines mostly drives the brake to close and press the brake disc through a magnetic brake to achieve braking. In heavy loads, only the friction method is used for braking. After the equipment has been used for a certain period of time, if the brake disc and other related equipment are not replaced in time, it is very easy to generate a smooth surface and cause slipping, thus affecting the braking effect.

[0007] Therefore, the present invention provides a traction machine with an integrated rope wheel housing to solve the problems that the geared traction machine has a large external size and is not easy to install and handle, and the safety problem that the pressing friction braking method is prone to slipping and crashing in heavy loads.

At one end of the active pull rod 19 away from the double-drive brake magnet 21, a stud is integrally provided. The diameter of the stud is smaller than the diameter of the active pull rod 19. A limit piece is inserted on the stud, and the limit piece abuts against the variable diameter connection of the stud and the active pull rod 19. A plurality of self-locking nuts one are screwed on the stud, and the self-locking nuts abut against the limit piece to brake the limit piece. A second spring 28 is sleeved on the active pull rod 19 between the limit piece and the first insertion cylinder 17, and the second spring 28 is always in a compressed state. On both sides of the mounting seat 13, a screw sleeve is provided. The side of the active pull rod 19 facing the mounting seat 13 is threaded and screwed into the screw sleeve to realize the connection between the active pull rod 19 and the mounting seat 13.

[0069] Straight groove holes 24 are provided at the bent portions of the two brake arms 14.

A first spring 27 is provided between the opposite ends of the two mounting shafts 25 and the mounting shafts 25 in the straight groove holes 24, and the first spring 27 is always in a compressed state.

[0070] A fixed shaft penetrates through the two brake arms 14. V-shaped rods 37 are rotatably mounted at both ends of the fixed shaft. A tension spring is provided between the V-shaped rods 37 and the brake arms 14. The lower ends of the V-shaped rods 37 always abut against the mounting shafts 25 under the pulling action of the tension spring. The upper ends of the two mounting rods are commonly connected to a U-shaped insertion frame 29. A brake disc 23 is fixedly mounted on the side of the traction wheel 12 facing the machine base 3 through fasteners. A plurality of brake blocks 30 are annularly arranged in the area near the outer edge surface of the brake disc 23.

[0071] 5. A heat dissipation component for dissipating heat inside the planetary reduction mechanism.

[0072] In this embodiment, an L-shaped pressing rod 22 is fixedly mounted on the mounting seat 13 through fasteners. There are two groups of pressing rods 22, which are symmetrically arranged on both sides of the horizontal center line of the traction wheel 12. By pressing the traction rope with the pressing rod 22, disordered stacking and winding are avoided.

[0073] In this embodiment, the distance between the inner wall of the second inserting cylinder 16 and the outer wall of the movable pull rod 19, and the universal joint 20 between the braking pull rod 18 and the output end of the double-drive brake magnet 21 are all for adjusting the movable distance when the braking arm 14 deflects. Or, a through vertical groove is provided on the side wall of the braking arm 14. U-shaped frames are fixedly installed at the ends of the movable pull rod 19 and the braking pull rod 18. Couplings are fixedly installed at the ends of the two arms of the U-shaped frame, and the couplings are inserted into the vertical groove to realize the connection between the movable pull rod 19, the braking pull rod 18 and the braking arm 14. Moreover, the connections at the ends of the movable pull rod 19 and the braking pull rod 18 can move on the braking arm, so that the connection between the movable braking arm 14 and the output end of the fixed double-drive brake magnet 21 can be realized without interfering with the movement.

[0074] In this embodiment, by controlling the length of the movable pull rod 19 screwed into the screw sleeve, the compressed distance of the first spring 27 can be adjusted, and then the pressure applied to the braking arm 14 can be adjusted, and then the pressing friction force of the brake shoe 15 on the brake disc 23 can be adjusted.

[0075] In this embodiment, the outer diameter of the second sun gear 11 is larger than the outer diameter of the first sun gear 7, so as to avoid interfering with the installation of the traction wheel 12.

[0076] In this embodiment, the shaft diameters (module) of the first planet gear 6, the output wheel 8, the input wheel 9, and the second planet gear 39 gradually increase, so as to achieve a gradual increase in the transmission ratio and the minimum transmission ratio is also greater than 1, realizing the effect of reducing the speed of the planetary reduction mechanism.

[0077] In this embodiment, referring to the attached Figure 18 As shown, the first planet carrier 5 and the second planet carrier 10 both include two face plates, and the two face plates are connected by welding with angle irons. The planet gears are dispersed between adjacent angle irons. The outer edge surface of the planet gear protrudes out of the face plate and meshes with the sun gear. The planet 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.

[0078] In this embodiment, the first planet gear 6, the output wheel 8, the second planet gear 39, and the input wheel 9 are all external gears, and the first sun gear 7 and the second sun gear 11 are both internal gears.

[0079] 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 adjacent brake blocks 30. To prevent the inserting frame 29 from deflecting relatively and shifting along the inclined plane when stressed.

[0080] In this embodiment, the friction plate is fixedly installed on the inner wall of the brake shoe 15 through countersunk head screws, so that the friction plate can be replaced to always maintain effective friction braking.

[0081] In this embodiment, the end of the insertion frame 29 is an arc-shaped protrusion. After the brake block 30 abuts against the insertion frame 29, the protrusion can play a certain role in preventing detachment.

[0082] Details of the principle of this embodiment:

[0083] During use, the driving host 2 drives the sleeve 4 to rotate through the cooperation of the spline and the spline groove. The sleeve 4 drives the first planet carrier 5 to rotate, and the first planet carrier 5 drives all the first planet gears 6 to perform a planetary motion. During the planetary motion of the first planet gears 6, they rotate around their own axes because they are meshed with the first sun gear 7. All the first planet gears 6 are also meshed with the output gear 8 to drive the output gear 8 to rotate. The output gear 8 drives the input gear 9 coaxially arranged to rotate. The input gear 9 drives all the second planet gears 39 to rotate around their own axes, and all the second planet gears 39 jointly drive the second sun gear 11 to rotate. The second sun gear 11 drives the traction wheel 12 to rotate, thereby realizing the winding or unwinding of the traction rope.

[0084] In the above process, the motion between the first planet gear 6 and the output gear 8, and between the input gear 9 and the output gear 8 are both deceleration motions, thereby reducing the input speed of the driving host 2. At the same time, the cooperation between the gears is used to amplify the torque, thereby reducing the output load requirement of the driving host 2 and realizing the large torque output of a small-power motor.

[0085] The planetary reduction mechanism in this solution is an improvement on the traditional planetary reduction mechanism. The final output of the traditional planetary reduction mechanism is the gear meshed inside the planet gear as the output shaft. In this solution, a two-stage planetary mechanism is adopted, and the rotation of the second sun gear 11 is used as the final output end. The two-stage planetary structure, compared with the power transmission of a single set of gears, not only realizes the torque shunt, 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 taking the second sun gear 11 as the output source, 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-bearing pulling area of the traction wheel 12 and improving the rotational stability of the traction wheel 12. And the traction wheel 12 is sleeved outside the planetary reduction mechanism, which can not only increase the axial length of the traction wheel 12, extend the length of the winding groove, and further increase the traction length; but also realize the hidden design of the planetary reduction mechanism, thereby reducing the external volume of the entire device, which is convenient for installation and handling.

[0086] When the traction wheel 12 stops, no current passes through the coil in the double-drive brake magnet 21. At this time, there is no attraction between the electromagnet cores, and the brake arm 14 approaches the brake disc 23 under the action of spring 1-27, causing the brake shoe 15 to tightly hold the brake disc 23. Through pressing friction, primary braking is achieved. During 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 presses spring 1-27 until it abuts against the limit block 26, and spring 1-27 is compressed. During the sliding process of the mounting shaft 25, it deflects along with the V-shaped rod 37, and the V-shaped rod 37 drives the insertion frame 29 to insert between the brake blocks 30 on the brake disc 23. Through the insertion of the insertion frame 29 between the brake blocks 30, secondary braking of the brake disc 23 is achieved. Compared with relying solely on pressing friction braking, this insertion braking method is more stable.

[0087] In this embodiment, a speed sensor is provided at the position of the corresponding bushing 4 within the machine base 3 for monitoring the output state of the drive host 2. The acceleration sensor and the control box of the drive motor are both electrically connected to the control box of the double-drive brake magnet 21. When the drive host 2 stops rotating, the bushing 4 stops, thereby sending a signal to the double-drive brake magnet 21 for braking, and braking is performed during static state. Before traction is required, before the drive host 2 rotates, the double-drive brake magnet 21 stops braking. After the braking is turned off, the drive host 2 starts to perform traction to avoid movement interference.

[0088] Embodiment 2, in the traditional planetary structure, the planetary gear makes a revolving motion, such as the first planetary gear 6 in this solution. When the drive host 2 is opened and closed, especially when starting, the revolving first planetary gear 6 will be impacted at the moment of starting and revolving, resulting in more serious wear of the first planetary gear 6 and shortening its service life. Therefore, in this solution, a different structure of the first planetary gear 6 is provided:

[0089] The first planetary gear 6 includes a gear body 31, a plurality of inner tooth plates 32, and a plurality of outer tooth plates 33.

[0090] The gear body 31 is rotatably installed at the center of the first planetary carrier 5. A plurality of inner tooth plates 32 and outer tooth plates 33 are arranged alternately, and a spacer 34 is provided between each adjacent inner tooth plate 32 and outer tooth plate 33, and spacers 34 are provided on the outer sides of both ends of the combination of the inner tooth plate 32 and the outer tooth plate 33. Both ends of the hub of the gear body 31 are clamped with a retaining cover 45, and the retaining cover 45 abuts against the outermost spacer 34. A clamping groove is provided on the outer edge surface of the shaft ends on both sides of the gear body 31, and a snap ring is embedded in the clamping groove. The snap ring abuts against the retaining cover 45 to limit the retaining cover 45. The outer tooth plate 33 and the inner tooth plate 32 are both made of high-strength and high-toughness metals, such as ultra-high-strength steel and transformation-induced plasticity steel (D&P steel).

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] According to the above technical solution:

[0096] When the temperature is not high, hot air is dissipated through the air inlet 35 and the air outlet 36 to dissipate heat spontaneously.

[0097] After the internal temperature gradually rises to a certain value, the thermally expanded gas in the expansion hole 44 continuously expands, thus pushing the sealing plug outward. The sealing plug drives the insertion block 43 to move outward until the insertion block 43 can be inserted into the insertion hole 42, so that the shaft sleeve 4 is connected to the wheel sleeve 40, and then drives the spiral fan blade 41 to rotate, forming an active wind force, accelerating the flow of hot air, and thus improving the heat dissipation effect. And it can be seen from the above embodiments that the input end of the planetary reduction mechanism has the fastest rotational speed, that is, the shaft sleeve 4 directly connected to the driving host 2 has the fastest rotational speed. Then the rotational speed of the spiral fan blade 41 cooperating with the shaft sleeve 4 is the fastest rotational speed in this device.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
