Description

Technical Field

[0001] This utility model belongs to the technical field of raft control equipment, specifically relating to a pendulum-type raft control machine. Background Technology

[0002] Raft control equipment is a common feature in water recreation facilities. Its function is to stop, fix, or launch rafts returning from slides or lazy rivers, or rafts ready to depart, according to management requirements, so that tourists can get on and off or the rafts can move around.

[0003] Currently, the departure and stopping of inflatable rafts, which involve fixing passengers on and off, are handled by two separate mechanisms. These mechanisms are complex, costly, prone to failure, and require complex maintenance and management. Furthermore, existing raft clamping mechanisms and launcher axes are vertically suspended, resulting in complex structures that are difficult to secure. Based on these shortcomings, this invention aims to design a simple, practical, and universal raft control mechanism. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pendulum raft control machine that can be used as both a launching machine and a stopping machine. It is horizontally arranged on the axis and placed at the bottom of the raft channel, with a simple structure and convenient installation.

[0005] The technical problem solved by this utility model is achieved through the following technical solution:

[0006] A pendulum-type raft control machine includes a front pendulum shaft seat and a rear pendulum shaft seat, both of which are fixedly installed at the bottom of a raft passage. A pendulum shaft is fitted between the front and rear pendulum shaft seats, with the axis of the pendulum shaft inclined to the axis of the raft passage. A raft control assembly is fixedly installed on the pendulum shaft. The raft control assembly includes a front clamping control roller, a rear clamping control roller, and a swing arm. The swing arm is fitted onto the pendulum shaft, and its end is connected to the front and rear clamping control rollers. A drive cylinder is hinged to the back of the raft control assembly via a joint. The rear end of the drive cylinder is hinged to a cylinder swing seat via a cylinder tailstock. The cylinder swing seat is fixed to the side wall of the raft passage. The drive cylinder drives the raft control assembly to swing. The front and rear clamping control rollers on the raft control assembly complete the interception, fixation, and release of rafts on the raft passage.

[0007] Furthermore, the angle between the axis of the swing shaft and the axis of the raft channel is 8 to 15°.

[0008] Furthermore, a rubber pad is fixedly installed on the side wall of the raft passage near the raft.

[0009] The positive effects that this utility model can produce are:

[0010] 1. This utility model achieves clamping control action through a swing structure: by selecting a reasonable position and size, the clamping control roller action is achieved through swinging.

[0011] 2. The swing shaft of this utility model is arranged horizontally: The existing boat clamping mechanism and boat launching machine have the axis arranged vertically suspended, which is complex and difficult to fix. In this example, the axis is arranged horizontally and placed at the bottom of the raft channel, which is simple in structure and easy to install.

[0012] 3. The swing axis of this utility model forms a certain angle with the side wall of the raft channel: The swing axis forms a certain angle with the side wall of the raft channel (the direction of raft movement), which realizes that the two clamping control rollers are staggered in all directions, so that the raft can pass smoothly through the front roller and be reliably stopped by the rear roller. When clamped and fixed, the two clamping control rollers match the outer circle of the raft and clamp the raft at the same time.

[0013] 4. This utility model replaces the existing four cylinders and two sets of clamping rollers with one driving cylinder: The existing boat clamping structure has two swing arms and four cylinders. This utility model achieves the function of two swing arms with one swing arm through reasonable structure and position selection, and one cylinder of the same size completes the function of four cylinders in the existing structure.

[0014] 5. This utility model can be used as both a ship launching machine and a ship stopping machine, making on-site maintenance simpler. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0024] like Figures 1-3 As shown, a pendulum-type raft control machine is innovative in that it includes a front pendulum shaft seat 1 and a rear pendulum shaft seat 2, both of which are fixedly installed at the bottom of the raft channel 3. A pendulum shaft 4 is fitted between the front pendulum shaft seat 1 and the rear pendulum shaft seat 2, and the axis of the pendulum shaft 4 is inclined to the axis of the raft channel 3. A raft control assembly is fixedly installed on the pendulum shaft 4. The raft control assembly includes a front clamping raft control roller 5, a rear clamping raft control roller 6, and a pendulum arm 7, which is fitted onto the bottom of the raft channel 3. On the swing shaft 4, the end of the swing arm 7 is connected to the front clamping control roller 5 and the rear clamping control roller 6. The back of the control assembly is hinged to the drive cylinder 8 through a joint. The rear end of the drive cylinder 8 is hinged to the cylinder swing seat 10 through the cylinder tail seat 9. The cylinder swing seat 10 is fixed on the side wall of the raft channel 3. The drive cylinder 8 drives the control assembly to swing. The front clamping control roller 5 and the rear clamping control roller 6 on the control assembly complete the interception, fixation and release of the raft 11 on the raft channel 3.

[0025] The axis of the swing shaft 4 is at an angle of 10° with the axis of the raft channel 3. The swing axis is at a certain angle with the side wall of the raft channel (the direction of raft movement), which realizes that the two clamping control rollers are staggered in all directions. The raft can pass smoothly through the front roller and be reliably stopped by the rear roller. When clamped and fixed, the two clamping control rollers are exactly matched with the outer circle of the raft and clamp the raft at the same time.

[0026] A rubber pad 12 is fixedly installed on the side wall of the raft channel 3 near the raft 11. When the raft is fixed, intercepted, or pushed out, the pad reduces the hard wear between the raft and the cement wall of the raft channel, extending the service life of the raft. At the same time, it increases the friction, making the raft easier to control and convenient to operate.

[0027] The working principle of this utility model is as follows:

[0028] The front and rear clamping control rollers on the raft control assembly are located on the side of the swing arm closest to the raft, with no components in between. This allows the control rollers to approach and even press into the raft. Due to the angle between the swing axis and the side wall of the raft channel, the two clamping control rollers are at different distances from the channel side wall. When there is no raft at the raft stop position, the control assembly is in the interception position, allowing the raft to pass smoothly through the first clamping control roller. However, the distance between the second clamping control roller and the channel side wall is less than the raft diameter, thus blocking the raft and placing it in an interception state. Figure 5 As shown;

[0029] When the sensor on the raft controller detects that the raft has been intercepted, the cylinder rod of the control drive cylinder continues to extend, and both clamping rollers press the raft tightly, fixing it in a fixed state. Figure 4 As shown;

[0030] When release is required, the drive cylinder lever retracts, the two clamping control rollers move away from the raft, and the raft continues to move forward under the action of the water flow. The raft is in the pushing and releasing state, as shown below. Figure 6 As shown, after the sensor detects that the raft has left the fixed position, the cylinder rod extends and clamps the raft control roller back to the interception position, waiting for the next action.

[0031] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
