Description

Technical Field

[0001] This invention relates to the field of mobile communication technology, and in particular to a mobile communication base station device. Background Technology

[0002] Mobile communication base station equipment, as a core communication tool ensuring signal coverage and transmission quality of wireless communication networks, is widely used in the construction of communication infrastructure in various scenarios such as cities and rural areas. To avoid occupying ground space, reduce direct interference to the surrounding environment, and optimize signal propagation range, a large number of existing mobile communication base station devices are installed on building rooftops. Their typical structure mainly consists of a pole, a transmitting device, and connecting components. The pole, as the supporting structure, needs to have a preset height to meet the space requirements for signal transmission. The transmitting device is fixedly assembled to the top of the pole through connecting components to achieve effective signal transmission and reception. During the long-term operation of base station equipment, factors such as equipment aging, signal technology upgrades, and communication capacity expansion necessitate regular maintenance and repair of the transmitting devices, or hardware upgrades and component replacements as required by the development of communication technology. However, based on the existing installation structure design of base station equipment, these maintenance and upgrade operations must be carried out manually: operators must use climbing tools to climb to the top of the pole and then disassemble the transmitting device and connecting components, or conduct maintenance operations directly at high altitudes. This type of operation has significant technical drawbacks: On the one hand, after manually climbing to a high altitude, the operation process of disassembly, maintenance, and reassembly is cumbersome due to the limited working space and the need to consider personal safety, resulting in low overall work efficiency. This not only affects the normal operation time of the communication network but also increases labor costs. On the other hand, the high-altitude working environment itself has safety hazards such as falls and injuries from falling parts, making it difficult to fully guarantee the personal safety of operators. Moreover, in severe weather conditions such as wind, rain, and low temperatures, the safety risks are further aggravated, causing great inconvenience to the maintenance and upgrade work. In summary, the existing mobile communication base station equipment installed on rooftops suffers from low efficiency and poor safety in its structural design, making it unable to meet the needs of efficient and safe operation and maintenance of communication infrastructure. Therefore, it is urgent to optimize and improve the relevant structure. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of the prior art by providing a mobile communication base station device.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The mobile communication base station equipment of the present invention includes a pole body and a transmitter body connected to the top of the pole body; The main body of the pole consists of an upper pole and a lower pole; the bottom end of the upper pole and the top end of the lower pole are hinged together by a second hinge pin; the main body of the launching device is connected to the top of the upper pole; A steel cable is fixed to the upper rod; the other end of the steel cable is on the lower rod; a baffle is provided at the bottom of the upper rod; when the upper rod and the lower rod are coaxial, the inner surface of the baffle is attached to the side wall of the lower rod.

[0005] Furthermore, the lower rod is provided with a pulley and an internally threaded sleeve; the pulley and the internally threaded sleeve are arranged from top to bottom along the height direction of the lower rod; a connecting ring is fixed to the bottom end of the steel cable; a bolt passes through the connecting ring and is threadedly connected to the internal thread of the internally threaded sleeve; the head of the bolt is pressed against the connecting ring.

[0006] Furthermore, a connector is fixed to the main body of the launching device; a first hinge shaft is fixed to the connector head; the first hinge shaft is hinged to the upper rod; the second hinge shaft is fixedly connected to the lower rod; a first synchronous pulley is fixed to the first hinge shaft; a second synchronous pulley is fixed to the second hinge shaft; and a transmission belt connects the first synchronous pulley and the second synchronous pulley.

[0007] Furthermore, the connector is a tubular structure with a sealed top; a side guide hole is provided on the side wall of the connector; a lateral extension shaft is slidably connected inside the side guide hole; an upper sleeve matching the connector is provided at the bottom of the main body of the launching device; the connector is inserted into the upper sleeve from bottom to top; an upper positioning hole matching the lateral extension shaft is provided on the inner side wall of the upper sleeve. The connector is internally equipped with an extension shaft drive module for driving the lateral extension shaft to slide within the side guide hole; when the connector rotates relative to the upper rod, it can drive the extension shaft drive module to move.

[0008] Furthermore, the extension shaft drive module includes an inner shaft slidably connected inside the connector and a spring disposed inside the connector; the two ends of the spring are respectively pressed against the inner top wall of the connector and the top of the inner shaft; a cam portion is provided at the top of the upper rod; the cam portion abuts against the bottom of the inner shaft; the lifting and lowering action of the inner shaft can drive the lateral extension shaft to perform a telescopic action.

[0009] Furthermore, the top end of the inner shaft is provided with a follower groove and a connecting block slot; a connecting block is provided on the lateral extension shaft and is slidably connected to the connecting block slot; a follower wheel is provided on the surface of the connecting block and is slidably connected to the follower groove; after the connecting block is inserted into the connecting block slot, the follower wheel is inserted into the follower groove.

[0010] Furthermore, the follower groove consists of an upper groove that extends through the top of the inner shaft at one end, an inclined groove that connects to the other end of the upper groove at one end, and a lower groove that connects to the other end of the inclined groove.

[0011] Furthermore, the cam portion is composed of a first cam surface and a second cam surface; the distance from the axis of the first hinge shaft to the second cam surface is a first distance; the magnitude of the first distance gradually decreases as it moves away from the first cam surface.

[0013] Furthermore, a support plate is provided on the connector head.

[0014] With the above structure, the beneficial effects of this invention are as follows: After the upper rod is erected, the upper rod and the lower rod are coaxial, and the end of the steel cable is directly fixed to the lower rod, so that the steel cable is fully taut. Using the traction force of the steel cable, the upper rod cannot rotate away from the side of the steel cable around the second hinge axis. Since the steel cable cannot provide support force, the baffle provides support force, so that the upper rod cannot rotate close to the steel cable around the second hinge axis, and the main body of the launching device is erected at the highest point. When it is necessary to upgrade or repair the main body of the launching device, the steel cable is loosened at one end of the lower rod, and the upper rod is tapped lightly, so that the upper rod generates an initial torque. The main body of the launching device and the upper rod generate a flipping torque under their own weight. Then, with the force of manually pulling the steel cable, the main body of the launching device and the upper rod slowly flip down to an easily accessible height. After maintenance or upgrades are completed, the main body of the launching device and the upper pole are flipped by pulling the steel cable until the upper and lower poles are coaxial. The end of the steel cable is then directly fixed to the lower pole to complete the positioning of the upper and lower poles. This structure allows the upper pole to be folded onto the lower pole through simple operation, eliminating the need for operators to climb to the top of the pole with climbing tools to carry out maintenance operations directly, thus improving maintenance efficiency and safety.

Detailed Implementation

[0016] The invention will now be further described with reference to the accompanying drawings.

[0017] like Figures 1 to 13 As shown, the mobile communication base station equipment of the present invention includes a pole body and a transmitter body 1 connected to the top of the pole body; The main body of the pole consists of an upper pole 4 and a lower pole 6; the bottom end of the upper pole 4 and the top end of the lower pole 6 are hinged together by a second hinge pin; the main body 1 of the launching device is connected to the top of the upper pole 4; A steel cable 7 is fixed to the upper rod 4; the other end of the steel cable 7 is on the lower rod 6; a baffle 401 is provided at the bottom of the upper rod 4; when the upper rod 4 and the lower rod 6 are coaxial, the inner surface of the baffle 401 is attached to the side wall of the lower rod 6. The main body of the launching device 1 is not fundamentally different from existing technologies, so it will not be described in detail here; The connection point between the upper pole 4 and the steel cable 7 and the baffle 401 are both located on the same side of the upper pole 4; a connecting ring 402 is provided at the connection point between the steel cable 7 and the upper pole 4, and the connecting ring 402 is used to bind and fix the steel cable 7 tightly. The bottom of the lower rod 6 is provided with a base 601 for connecting with the concrete structure; the lower rod 6 is fixedly connected to the concrete structure by bolts passing through the through holes of the base 601, so that the lower rod 6 is fixed to the concrete structure on the roof. In addition, to ensure safety, during installation, it is necessary to consider that after the upper rod 4 is folded, it should be flipped towards the building floor to ensure that after the upper rod 4 flips and descends, the main body 1 of the launching device lands directly above the floor, so that the staff can operate the main body 1 of the launching device directly from the roof; the upper rod 4 is a hollow rod to reduce the gravity above the lower rod 6. After the upper rod 4 is erected, the upper rod 4 and the lower rod 6 are coaxial, and the end of the steel cable 7 is directly fixed to the lower rod 6, so that the steel cable 7 is fully taut. Using the traction force of the steel cable 7, the upper rod 4 cannot rotate away from the side of the steel cable 7 around the second hinge axis. Since the steel cable 7 cannot provide support force, the baffle 401 provides support force, so that the upper rod 4 cannot rotate close to the steel cable 7 around the second hinge axis, and the main body 1 of the launching device is erected at the highest point. When it is necessary to upgrade or repair the main body 1 of the launching device, loosen the steel cable 7 at one end of the lower rod 6, and gently tap the upper rod 4 to generate an initial torque on the upper rod 4. The main body 1 of the launching device and the upper rod 4 will generate a flipping torque under their own weight. Then, with the force of manually pulling the steel cable 7, the main body 1 of the launching device and the upper rod 4 will slowly flip down to an easily accessible height.

[0018] After maintenance or upgrade, the main body 1 of the launching device and the upper rod 4 are flipped by pulling the steel cable 7 until the upper rod 4 and the lower rod 6 are coaxial. The end of the steel cable 7 is directly fixed to the lower rod 6 to complete the positioning of the upper rod 4 and the lower rod 6. This structure allows the upper pole 4 to fold onto the lower pole 6 through simple operation, eliminating the need for operators to climb to the top of the pole with climbing tools to carry out maintenance operations directly, thus improving maintenance efficiency and safety.

[0019] In a preferred embodiment of the present invention, the lower rod 6 is provided with a pulley 8 and an internally threaded sleeve 602; the pulley 8 and the internally threaded sleeve 602 are arranged from top to bottom along the height direction of the lower rod 6; a connecting ring 701 is fixed to the bottom end of the steel cable 7; a bolt 9 passes through the connecting ring 701 and is threadedly connected to the internal thread of the internally threaded sleeve 602; the head of the bolt 9 is pressed against the connecting ring 701; Both sides of the pulley 8 are equipped with baffles to prevent the steel cable 7 from coming loose from the sides of the pulley 8; after the middle of the steel cable 7 passes around the pulley 8, the pulley 8 reverses the direction of the steel cable 7 so that the distance from the position of the steel cable 7 at the pulley 8 to the lower rod 6 is greater than the distance from the end of the internal thread sleeve 602 to the lower rod 6, thus folding the steel cable 7 into a "<" shaped structure; After passing through the connecting ring 701, the bolt 9 is threaded into the internal thread of the internal thread sleeve 602, so that the bottom end of the steel cable 7 is fixed to the internal thread sleeve 602. When the steel cable 7 is tightened, the tightness of the steel cable 7 can be finely adjusted by rotating the bolt 9 to ensure that the inner surface of the baffle 401 is in contact with the side wall of the lower rod 6, thereby improving the coaxiality of the upper rod 4 and the lower rod 6.

[0020] In a preferred embodiment of the present invention, a connector 2 is fixed on the main body 1 of the launching device; a first hinge shaft is fixed on the connector 2; the first hinge shaft is hinged to the upper rod 4; the second hinge shaft is fixedly connected to the lower rod 6; a first synchronous pulley 201 is fixed on the first hinge shaft; a second synchronous pulley 603 is fixed on the second hinge shaft; and a transmission belt 5 is connected between the first synchronous pulley 201 and the second synchronous pulley 603. The first hinge shaft is directly fixed to the lower connecting plate 205; In practical applications, the module composed of the first synchronous pulley 201, the second synchronous pulley 603 and the transmission belt 5 is protected by the protective cover set on the upper rod 4. The first synchronous pulley 201 and the second synchronous pulley 603 are synchronous belt pulleys or sprockets of the same specifications; when the first synchronous pulley 201 and the second synchronous pulley 603 are synchronous belt pulleys, the transmission belt 5 is a synchronous belt tensioned between the two synchronous belt pulleys; when the first synchronous pulley 201 and the second synchronous pulley 603 are sprockets, the transmission belt 5 is a transmission chain tensioned between the two sprockets. In addition to rotatably connecting the upper rod 4 and the connector 2, the first hinge shaft is also used to fix the first synchronous wheel 201 to the connector 2. In addition to rotatably connecting the lower rod 6 and the upper rod 4, the second hinge shaft is also used to fix the second synchronous pulley 603 onto the lower rod 6. When the upper rod 4 and the lower rod 6 rotate relative to each other, since the second synchronous pulley 603 is fixed on the lower rod 6, it is stationary relative to the lower rod 6. Therefore, the rotation of the second synchronous pulley 603 relative to the upper rod 4 is equivalent to the rotation direction of the second synchronous pulley 603 being opposite to the swing direction of the upper rod 4. Since the transmission belt 5 is positioned on the upper rod 4, the second synchronous pulley 603 and the transmission belt 5 will move relative to each other. This is equivalent to the second synchronous pulley 603 driving the transmission belt 5 to move relative to the upper rod 4, causing the first synchronous pulley 201 to rotate relative to the upper rod 4, thus realizing the rotation of the connector 2 and the main body 1 of the launching device. In addition, since the first synchronous pulley 201 and the second synchronous pulley 603 are of the same specification, the angle of rotation of the second synchronous pulley 603 relative to the upper rod 4 is equal to the angle of rotation of the first synchronous pulley 201 relative to the upper rod 4. Furthermore, the rotation direction of the connector 2 and the main body 1 of the launching device is opposite to the swing direction of the upper rod 4. Therefore, the connector 2 and the main body 1 of the launching device will rotate relative to the upper rod 4, so that the connector 2 always faces vertically upwards no matter what angle the upper rod 4 rotates to.

[0021] To avoid the risk of damage to internal components due to the flipping of the main body 1 of the launching device, and to prevent the main body 1 of the launching device from directly impacting the ground when the upper rod 4 flips over; it always keeps the launching device main body 1 in an upright position, which facilitates the assembly and disassembly of the launching device main body 1.

[0022] In a preferred embodiment of the present invention, the connector 2 is a tubular structure with a sealed top; a side guide hole 203 is provided on the side wall of the connector 2; a lateral extension shaft 3 is slidably connected inside the side guide hole 203; an upper sleeve 101 matching the connector 2 is provided at the bottom of the main body 1 of the launching device; the connector 2 is inserted into the interior of the upper sleeve 101 from bottom to top; an upper positioning hole 102 matching the lateral extension shaft 3 is provided on the inner side wall of the upper sleeve 101. The connector 2 is internally provided with an extension shaft drive module for driving the lateral extension shaft 3 to slide within the side guide hole 203; when the connector 2 rotates relative to the upper rod 4, it can drive the extension shaft drive module to move. An insertion guide groove 103 is provided on the inner surface of the upper sleeve 101. The insertion guide groove 103 is used to guide the lateral extension shaft 3 when it is inserted. An insertion limiting strip 202 is provided on the outer side wall of the connector 2, and an insertion limiting groove 104 matching the insertion limiting strip 202 is provided on the inner side wall of the upper sleeve 101. After the connector 2 is inserted into the upper sleeve 101, the insertion limiting strip 202 is also inserted into the insertion limiting groove 104, so that the upper sleeve 101 cannot rotate on the connector 2. This ensures that the lateral extension shaft 3 can be accurately inserted into the upper positioning hole 102. When the entire launching device body 1 needs to be removed, the extension shaft drive module can be activated by rotating the connector 2 relative to the upper rod 4, so that the lateral extension shaft 3 can be inserted into the upper positioning hole 102 or extended out of the upper positioning hole 102.

[0023] In a preferred embodiment of the present invention, the extension shaft drive module includes an inner shaft 11 slidably connected inside the connector 2 and a spring 10 disposed inside the connector 2; the two ends of the spring 10 are respectively pressed against the inner top wall of the connector 2 and the top of the inner shaft 11; a cam portion 403 is disposed at the top of the upper rod 4; the cam portion 403 abuts against the bottom of the inner shaft 11; the lifting and lowering action of the inner shaft 11 can drive the lateral extension shaft 3 to perform a telescopic action; An inner shaft guide block 1101 is provided on the inner shaft 11; the inner cavity of the connector 2 is provided with a directional groove 206 that matches the inner shaft guide block 1101; after the lateral extension shaft 3 is inserted into the side guide hole 203, the inner shaft guide block 1101 is inserted into the directional groove 206 to reduce the axial pressure received by the lateral extension shaft 3. When the upper rod 4 and the lower rod 6 rotate relative to each other, the connector 2 rotates relative to the upper rod 4 until the upper rod 4 and the lower rod 6 are coaxial. Under the action of the cam part 403 and the spring 10, the inner shaft 11 is pushed to a certain position in the connector 2. At this position, the inner shaft 11 causes the lateral extension shaft 3 to extend into the upper positioning hole 102, thus fastening the main body 1 of the launching device to the connector 2. When the main body 1 of the launching device is about half a meter away from the surface of the roof, the connector 2 rotates relative to the upper rod 4. Under the action of the cam part 403 and the spring 10, the inner shaft 11 is pushed to another position in the connector 2. The inner shaft 11 causes the lateral extension shaft 3 to retract into the inner guide hole 203, without obstructing the upper sleeve 101 from being pulled out of the connector 2. In this structure, the connector 2 and the transmitter body 1 are self-locked by flipping the upper rod 4 and the lower rod 6 to coaxial position. After the upper rod 4 and the lower rod 6 are flipped to form an acute angle, the connector 2 and the transmitter body 1 are automatically released. When the mobile communication base station equipment is upright, the self-locking can be achieved without operating the connection between the connector 2 and the transmitter body 1. When the mobile communication base station equipment is folded for maintenance, the connector 2 and the transmitter body 1 are automatically released, and the equipment can be removed without additional operation, improving the efficiency of disassembly and assembly and making the maintenance of the equipment more convenient.

[0024] In a preferred embodiment of the present invention, the top end of the inner shaft 11 is provided with a follower groove 1102 and a connecting block slot 1103; the lateral extension shaft 3 is provided with a connecting block 301 that is slidably connected to the connecting block slot 1103; the surface of the connecting block 301 is provided with a follower wheel 302 that is slidably connected to the follower groove 1102; after the connecting block 301 is inserted into the connecting block slot 1103, the follower wheel 302 is inserted into the follower groove 1102; the cam part 403 rotates in conjunction with the spring 10 to drive the inner shaft 11 to move up and down in the inner cavity of the connector 2. During the up and down movement of the inner shaft 11, the follower groove 1102 pushes the follower wheel 302, so that the lateral extension shaft 3 slides in the inner guide hole 203.

[0025] As a preferred embodiment of the present invention, the follower groove 1102 is composed of an upper groove 110201 that passes through the top of the inner shaft 11 at one end, an inclined groove 110202 that is connected to the other end of the upper groove 110201 at one end, and a lower groove 110203 that is connected to the other end of the inclined groove 110202. When the inner shaft 11 moves up and down in the inner cavity of the connector 2, the follower wheel 302 will enter the upper groove 110201, the inclined groove 110202 and the lower groove 110203 respectively; when the follower wheel 302 is in the upper groove 110201, the extension of the lateral extension shaft 3 is at its minimum, and the lateral extension shaft 3 is completely retracted into the inner guide hole 203; when the follower wheel 302 moves in the inclined groove 110202, the lateral extension shaft 3 slides along the inner guide hole 203; when the follower wheel 302 is at any position in the lower groove 110203, the end of the lateral extension shaft 3 extends out of the inner guide hole 203 and is inserted into the upper positioning hole 102.

[0026] In a preferred embodiment of the present invention, the cam portion 403 is composed of a first cam surface 40301 and a second cam surface 40302; the distance from the axis of the first hinge shaft to the second cam surface 40302 is a first distance; the magnitude of the first distance gradually decreases as it moves away from the first cam surface 40301. The first cam surface 40301 is an arc-shaped surface coaxial with the first hinge shaft. When the inner shaft 11 contacts the first cam surface 40301, the height of the inner shaft 11 is pushed to the highest point. When the second cam surface 40302 contacts the inner shaft 11 and the inner shaft 11 gradually moves away from the first cam surface 40301, the inner shaft 11 gradually descends in the inner cavity of the connector 2.

[0027] In a preferred embodiment of the present invention, the bottom surface of the inner shaft 11 is provided with an arcuate surface 1104; the arcuate surface 1104 abuts against the surface of the cam portion 403.

[0028] The curved surface 1104 can reduce the resistance when the inner shaft 11 slides relative to the cam portion 403.

[0029] In a preferred embodiment of the present invention, the connector 2 is provided with a support plate 204; the support plate 204 is used to support and limit the upper sleeve 101, and to align the lateral extension shaft 3 with the upper positioning hole 102 when the upper sleeve 101 is assembled with the connector 2.

[0030] Beneficial effects of this invention: 1. The upper pole can be folded onto the lower pole through simple operation, eliminating the need for operators to climb to the top of the pole with climbing tools to carry out maintenance operations directly, thus improving maintenance efficiency and safety.

[0031] 2. When the upper rod is folded down, the main body of the launching device remains upright, avoiding the risk of damage to internal components due to the flipping of the launching device. It also prevents the main body of the launching device from directly impacting the ground when the upper rod is flipped, making it convenient to disassemble and assemble the main body of the launching device.

[0032] 3. When the mobile communication base station equipment is upright, it can achieve self-locking without operation of the connection between the connector and the main body of the transmitter. When the mobile communication base station equipment is folded for maintenance, the connector and the main body of the transmitter will automatically loosen and can be removed without additional operation, improving the efficiency of equipment disassembly and assembly and making equipment maintenance more convenient.
