Description

Technical Field

[0001] The utility model relates to the technical field of road barriers, and more specifically to an intelligent road barrier. Background Art

[0002] There are usually gates at the entrances of enterprises, institutions, public places or communities. For the convenience of opening, many gates are electric gates. Traditional electric gates include telescopic doors and sliding doors. They are opened and closed by driving the door row to extend / expand in the horizontal plane or to open horizontally in the horizontal plane through a driving mechanism. They have the problem of occupying a large space. As a new type of electric door, the vertical rotating electric door drives the door row to extend / expand in the vertical plane through a driving mechanism to open and close the door, thus avoiding the problem of traditional electric doors occupying a large space. For example, the Chinese patent authorization announcement number CN106761352B discloses a symmetrical balancing structure for a vertically rotating electric door, which is provided with a drive mechanism chassis for accommodating a drive mechanism and a balancing mechanism chassis for accommodating a balancing mechanism at intervals and symmetrically, and the drive mechanism and the balancing mechanism are respectively connected to a main shaft provided at the upper part between the drive mechanism chassis and the balancing mechanism chassis, and a door row assembly is provided on the main shaft, and the door row assembly is driven by the main shaft to rotate vertically under the drive of the drive mechanism, and the door row assembly is generated by the balancing mechanism during the rotation process. The reverse torque that is balanced with the door row assembly makes the door row assembly rise and fall smoothly. The balancing mechanism of this patent changes the size of the spring assembly force arm through the spring hanging arm, so that the torque generated by the spring assembly on the main shaft is a reverse torque that is balanced with the torque generated by the door row assembly on the main shaft, reducing the load of the drive mechanism, which is not only conducive to saving operating costs, but also can extend the service life of the drive mechanism. However, the disadvantage is that in order to prevent the movement trajectory of the transmission assembly from deviating during the rotation of the spring hanging arm, a guide device is provided between the spring assembly and the spring hanging arm, which cooperates with the transmission assembly. The guide device is a sprocket or a guide wheel; its structure is complex, the cost is high, there is a certain degree of disturbance, the friction is large, and there is abnormal noise during operation. Therefore, it is necessary to further improve the existing technology. Summary of the invention

[0004] The utility model adopts the following technical solutions to achieve the above-mentioned purpose: an intelligent highway gate, including a door row assembly, a driving mechanism chassis for accommodating a driving mechanism and a balancing mechanism chassis for accommodating a balancing mechanism, the driving mechanism and the balancing mechanism are connected to the door row assembly through a main shaft, and the door row assembly is driven by the driving mechanism to rotate vertically through the main shaft. It is characterized in that the balancing mechanism includes a spring assembly, a transmission chain, and a chain arm, the chain arm is connected to the main shaft, and a plurality of rollers are arranged on the transmission chain, which are rollingly connected to the chain arm, the rollers are small in size, have almost no disturbance deformation, run quietly, and have low cost.

[0005] As a further illustration of the above solution, a guide track is arranged outside the chain hanging arm, and the rollers of the transmission chain rotate relatively on the guide track.

[0006] Furthermore, the main shaft is centrally located, and the guide track is provided with an arc-shaped guide surface, so that the transmission chain guided by the guide track can extend vertically downward.

[0007] Furthermore, the spindle position is not centered left to right, but the transmission chain position is centered.

[0008] Furthermore, two groups of mounting holes for mounting handles are provided on the chassis, and the two groups of mounting holes are arranged up and down. A pair of handles can be installed on the top or on the bottom. The handles are fixed on the top when manually moved on the installation site without conditions. If there is an electric forklift, the carrying handles are installed below, and the forklift lifting platform can be adjusted to a suitable width for carrying with the electric forklift. If there is a crane, the crane can also be used to pass the lifting rope through the two carrying handles for carrying.

[0009] Furthermore, the driving mechanism adopts a DC brushless motor, a travel switch is connected to the motor power line of the DC brushless motor, the tail of the DC brushless motor's rotating shaft is exposed outside its motor housing, and a crank is provided on the movable sleeve at the tail of the rotating shaft; when manual drive is required, the crank triggers the travel switch and the motor power line is in a disconnected state.

[0010] Furthermore, the travel switch is replaced by a micro switch or a photoelectric switch.

[0011] The beneficial effects that can be achieved by the utility model by adopting the above technical solution are:

[0013] In view of the problem that a chassis weighing more than 300 kilograms is difficult to carry, the utility model provides two groups of mounting holes on the chassis, and a pair of handles can be installed on the upper part or on the lower part. The handles are fixed on the upper part when manually carrying the chassis on the installation site under unconditional conditions; if an electric forklift is available, the carrying handles are installed on the lower part, the forklift lifting platform can be adjusted to a suitable width, and the chassis can be carried by the electric forklift. If a crane is available, the crane can also be used to pass a lifting rope through the two handles for carrying.

[0014] The utility model aims at the potential safety hazard in the prior art when the gate machine manually drives the gate rod to the gate opening position by using a crank handle during a power outage, and adds a protective device, which is manifested as: using a travel switch to directly control the power line of the motor, when manual drive is required, the crank handle triggers the travel switch, and the power line of the motor is in a disconnected state, so that the problem of the motor rotating suddenly due to power supply and the high-speed rotation injuring the hand will not occur.

[0025] The following is a further description of the specific implementation of the utility model in conjunction with the drawings of the specification, so that the technical solution and its beneficial effects of the utility model are clearer and more explicit. The following description of the embodiments with reference to the drawings is exemplary and intended to explain the utility model, and cannot be understood as limiting the utility model.

[0026] like Figure 1-Figure 3 As shown, the utility model is an intelligent highway gate, comprising a door row assembly 1, a driving mechanism chassis 2 for accommodating a driving mechanism 10, and a balancing mechanism chassis 3 for accommodating a balancing mechanism 5, wherein the driving mechanism chassis and the balancing mechanism chassis are symmetrically arranged and spaced apart from each other. The driving mechanism and the balancing mechanism are connected to the door row assembly 1 through a main shaft 4, and the door row assembly is driven by the driving mechanism to rotate vertically through the main shaft, and during the rotation of the door row assembly, the balancing mechanism generates a reverse torque that is balanced with the door row assembly to make the door row assembly rise and fall smoothly.

[0027] The balancing mechanism 5 includes a spring assembly 5-1, a transmission chain 5-2, and a chain hanging arm 5-3. The spring assembly of this embodiment is composed of multiple springs, and one end of each spring is fixed to the bottom of the balancing mechanism chassis, and the other end is connected to the transmission chain. The chain hanging arm is connected to the main shaft, and a plurality of rollers 5-21 are provided on the transmission chain 5-2, which are rollingly connected to the chain hanging arm. The rollers are small in size, almost without disturbance deformation, quiet operation, and low cost. In this embodiment, a guide track 6 is provided outside the chain hanging arm, and the rollers 5-21 of the transmission chain 5-2 rotate relatively on the guide track 6; the main shaft is centered, and the guide track is provided with an arc-shaped guide surface, so that the transmission chain guided by the guide track can extend vertically downward. It is worth noting that an alternative solution can also be adopted, in which the main shaft is not centered on the left and right, so that the transmission chain is centered. When the chain hanging arm rotates, the swing amplitude of the transmission chain is not large and can be ignored, and no guide wheel or guide track is required.

[0028] like Figure 2 As shown, two groups of mounting holes for mounting handles 7 are provided on the chassis, and the two groups of mounting holes are arranged up and down. A pair of handles can be installed on the upper part or on the lower part. The handles are fixed on the upper part when they are manually moved on the installation site without conditions. If there is an electric forklift, the carrying handles are installed on the lower part, and the forklift lifting platform can be adjusted to a suitable width for carrying with the electric forklift. If there is a crane, the crane can also be used to pass the lifting rope through the two carrying handles for carrying.

[0029] The driving mechanism adopts a brushless DC motor, which is connected to a reducer, and the output end of the reducer is connected to the main shaft, wherein the brushless DC motor is a safe low-voltage 24V motor. Figure 4 and Figure 5 As shown, a travel switch is connected to the motor power line of the brushless DC motor, the rear end of the shaft of the brushless DC motor is exposed outside the motor housing, and a crank 8 is provided on the rear end of the shaft; when manual drive is required, the crank triggers the travel switch 9, and the motor power line is disconnected. For greater safety, the travel switch can be replaced with a micro switch or a photoelectric switch. When a photoelectric switch is used, when the crank is inserted into the rear end of the motor, the photoelectric control circuit is blocked from being turned on and off.

[0030] Compared with the prior art, the utility model adopts a plurality of rollers arranged on the transmission chain, which are rollingly connected with the chain hanging arm, the rollers are small in size, almost free of disturbance deformation, quiet in operation and low in cost; two groups of mounting holes are arranged on the chassis, a pair of handles can be installed on the upper part or on the lower part, and the handles are fixed on the upper part when manually carried on the installation site without conditions; if there is an electric forklift, the carrying handles are installed on the lower part, the forklift lifting platform can be adjusted to a suitable width, and the electric forklift can be used for carrying, and a crane can also be used to pass the lifting rope through the two handles for carrying; when the power is off, the gate machine uses a crank to manually drive the gate rod to the opening position, which is a safety hazard. The travel switch is used to directly control the power line of the motor. When manual drive is required, the crank triggers the travel switch, and the power line of the motor is in a disconnected state, so there will be no problem of injuring the hand due to sudden power supply and high-speed rotation of the motor.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
