[0002] As an important component of the launch equipment, the vertical adjustment mechanism reducer is set at the lower part of the launch platform. It is used to adjust the horizontality of the launch platform to ensure the verticality of the rocket body, thereby realizing the conversion between the walking state and the launching state of the movable launch platform.

[0003] When the launch platform is undergoing maintenance, inspection, or hoisting at a technical position, or undergoing testing or refueling at a mobile launch station, the vertical adjustment mechanism's reducer increases torque to transmit power to the foundation, causing it to lift the launch platform and free the launch platform's wheels from the ground track.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0036] Example 1

[0037] See also Figure 1 and Figure 2 As shown, the vertical adjustment mechanism reducer provided in the present application is used for launching equipment, specifically for lifting or lowering the launching platform. The vertical adjustment mechanism reducer can adjust the launching platform to a horizontal state so that the arrow body it carries is in a vertical state.

[0038] Specifically, the vertical adjustment mechanism reducer includes a reducer body 101, a sensor assembly, and a controller. The reducer body 101 is a vertical structure and includes two drive units and a conversion unit, namely a manual drive unit 102 and an electric drive unit 106, respectively, provided on either side of the reducer body 101.

[0039] The manual drive part 102 includes a handle 103 and a first bevel gear 104 connected to each other. Rotating the handle 103 can drive the first bevel gear 104 to rotate. The conversion part is a horizontally arranged steering bevel gear 105. The first bevel gear 104 is meshed and connected with the steering bevel gear 105 on the left side. Rotating the first bevel gear 104 can drive the steering bevel gear 105 to rotate.

[0040] The electric drive unit 106 includes a connected connector 107 and a second bevel gear 108. The connector 107 is provided with an installation port 109 that can be connected to a drive device (specifically a hydraulic motor). The output end of the drive device can drive the connector 107 and the second bevel gear 108 to rotate. The second bevel gear 108 is meshed and connected with the steering bevel gear 105. The rotation of the second bevel gear 108 can drive the steering bevel gear 105 to rotate.

[0041] The reducer body 101 also includes a transmission assembly, and the steering bevel gear 105 is connected to the transmission assembly to transmit power. The transmission assembly specifically includes a first-stage planetary gear set (including a first-stage sun gear 110, a first-stage planetary gear 111, a first-stage planetary carrier 112 and a first-stage inner ring gear 113) and a second-stage planetary gear set (including a second-stage sun gear 114, a second-stage planetary gear 115, a second-stage planetary carrier 116 and a second-stage inner ring gear 117). An internal spline is provided at the bottom of the second-stage planetary carrier 116, and power can be output from the internal spline. The launch platform is connected to the internal spline to achieve a lifting effect.

[0042] An oil reservoir 118 is located on top of the reducer body 101. This reservoir is used to replenish lubricating oil in the transmission assembly to ensure smooth operation of the primary and secondary planetary gear sets. The sensor assembly includes a height sensor 119 and a wiring socket 120. Height sensor 119 is mounted within oil reservoir 118 of the reducer body 101. The rod of height sensor 119 is connected to the secondary planetary carrier 116 of the reducer body 101. Height sensor 119 is internally equipped with a sliding resistor. Rotation of the secondary planetary carrier 116 causes the resistance value of height sensor 119 to change proportionally.

[0043] Wiring socket 120 is mounted on top cover 121 of oil tank 118. Top cover 121 defines a connection hole. One end of wiring socket 120 is inserted into oil tank 118 through the connection hole and electrically connected to height sensor 119 via wire 122. The other end of wiring socket 120 is located outside oil tank 118 and electrically connected to the controller. Preferably, wiring socket 120 is also covered by a removable protective cover 123, which is mounted on the outside of top cover 121 of oil tank 118. This protects wiring socket 120 from dust and damage.

[0044] Because the number of rotations of the driver, the height of the launch platform, and the change in the resistance of height sensor 119 all change in equal proportion, the controller can obtain the change in the resistance of height sensor 119 and output the height of the launch platform. If the height of the launch platform is known, the number of rotations of the driver can also be obtained, thereby instructing the driver to input the corresponding number of rotations.

[0045] The vertical adjustment mechanism reducer provided in the present application, by setting a height sensor 119 on the reducer body 101, can accurately adjust the height of the launch platform when the launch platform is lifted, so that the level of the launch platform after lifting is higher, ensuring that the rocket body on the launch platform is vertical, and further ensuring that the subsequent rocket body launch process is safe and reliable.

[0046] In an optional solution of this embodiment, the sensor assembly also includes a speed measuring shaft 124, and the secondary planetary carrier 116 is provided with a mounting hole, the center line of the mounting hole is collinear with the rotation axis of the planetary carrier; the speed measuring shaft 124 is installed in the mounting hole, and the speed measuring shaft 124 rotates synchronously with the secondary planetary carrier 116, and the top end of the speed measuring shaft 124 is connected to the rod portion of the height sensor 119 to drive the rod portion of the height sensor 119 to rotate, thereby changing the resistance value of the height sensor 119.

[0047] Among them, the first-stage planetary gear set and the second-stage sun gear 114 are provided with a through hole 125, the speed measuring shaft 124 passes through the through hole 125, and the speed measuring shaft 124 and the through hole 125 are clearance-fitted, and the top end of the speed measuring shaft 124 is connected to the rod of the height sensor 119.

[0048] Specifically, a pin 126 is provided at the top of the speed measuring shaft 124 , and a groove is correspondingly provided on the rod of the height sensor 119 . The pin 126 is embedded in the groove, and the rotation of the speed measuring shaft 124 can drive the rod of the height sensor 119 to rotate.

[0049] In an optional solution of this embodiment, a limiting ball top 127 is provided at the bottom end of the speed measuring shaft 124, and the mounting hole opened in the secondary planetary carrier 116 is a blind hole. The limiting ball top 127 is installed in the mounting hole, and power can be transmitted to the speed measuring shaft 124 via the limiting ball top 127; the limiting ball can support and limit the secondary sun gear 114 from the bottom without affecting the rotation of the secondary sun gear 114.

The technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0052] If the electrical components of height sensor 119 are immersed in lubricating oil for a long time, they are prone to malfunction, causing damage to height sensor 119. In an optional solution of this embodiment, the sensor assembly also includes a separator bracket 128; separator bracket 128 is installed in oil storage tank 118, and separator bracket 128 acts as a partition structure to separate the cavity of oil storage tank 118 into a lower oil storage chamber 129 and an upper oil-free chamber 130. The lower oil storage chamber 129 can communicate with the transmission assembly, without affecting the function of replenishing lubricating oil to the transmission assembly.

[0053] The height sensor 119 is mounted on a partition bracket 128, which can support and fix the height sensor 119; the head of the height sensor 119 is located in the oil-free chamber 130 to avoid damage due to oil immersion, and the rod of the height sensor 119 passes through the partition bracket 128 to connect to the speed measuring shaft 124 to realize the measurement function.

[0054] In an optional solution of this embodiment, as shown in the figure, in order to reliably fix the partition bracket 128, a stepped platform 131 is provided on the side wall of the oil storage tank 118, and the circumference of the partition bracket 128 can be overlapped and installed on the stepped platform 131.

[0055] Specifically, the spacer bracket 128 includes a connected cover plate 132 and a bracket body 133. Specifically, the cover plate 132 and the bracket body 133 are provided with corresponding threaded holes. After applying an appropriate amount of thread glue, the cover plate 132 and the bracket body 133 can be connected. The bracket body 133 protrudes upward to form a cavity of a certain height, which can accommodate the rod portion of the height sensor 119 of a certain length.

[0056] The cover plate 132 is mounted on the stepped platform 131 and is provided with a stepped mounting surface corresponding to the stepped platform 131. A sealing structure is provided between the cover plate 132 and the stepped platform 131. Specifically, the sealing structure can be an O-ring. A sealing groove is provided on the sealing end surface of the cover plate 132. The O-ring is greased and installed in the sealing groove. An appropriate amount of sealant can be applied to the sealing end surface of the cover plate 132 before connecting it to the stepped platform 131. Specifically, threaded holes are provided on the cover plate 132 and the stepped platform 131. The screws are greased with a suitable amount of thread glue to connect the cover plate 132 to the stepped platform 131.

[0057] The cover plate 132 defines a first through-hole, through which the speed measuring shaft 124 extends, allowing it to connect to the rod of the height sensor 119. The first through-hole also serves as a position limiter for the speed measuring shaft 124. The bracket body 133 defines a second through-hole, through which the rod of the height sensor 119 extends and connects to the speed measuring shaft 124. A locking nut 134 is provided on the side of the second through-hole facing away from the oil-free chamber 130 to secure the head of the height sensor 119 to the second through-hole.

[0058] In an optional solution of this embodiment, the speed measuring shaft 124 is provided with a limit ring 135, which is located on the side of the oil storage chamber 129 to limit the depth of the speed measuring shaft 124 extending into the first through hole, that is, at the top of the speed measuring shaft 124, the limit ring 135 can limit the axial direction of the speed measuring shaft 124.
