Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of connection between a tugboat and a barge (referring to a tugboat and a barge to realize transportation along a river bank), and specifically relates to a connection device for connecting a transport tugboat and a barge. Background Art
[0002] At present, in water transportation, barges and transport tugboats are mostly connected by steel cables or ropes. This traditional flexible cable connection is easy to break when the transport tugboat is traveling at high speed. The cable cannot buffer the sudden increase in impact force during acceleration, deceleration or sudden turning, which can easily cause problems such as collision between the transport tugboat and the barge, and the falling of transported goods. In addition, some barges and transport tugboats use rigid connections and only use springs for single-degree-of-freedom buffering. However, during actual navigation, the transport tugboat will experience six degrees of freedom shaking, including longitudinal swing, lateral swing, vertical swing, pitch, roll and bow swing. When the transport tugboat is traveling at high speed, the buffering angle is single and the buffering is insufficient, which can easily cause problems such as breakage of the connection device and collision between the transport tugboat and the barge.

[0027] The utility model will be further described below in conjunction with the accompanying drawings: It should be emphasized that the embodiments described in the utility model are illustrative rather than restrictive, so the utility model is not limited to the embodiments described in the specific implementation manner, and any other implementation manners derived by technical personnel in this field based on the technical solution of the utility model also fall within the scope of protection of the utility model.
[0028] A connection device for connecting a transport tugboat and a barge includes: a horizontal swing buffer module, a vertical bump buffer module and a front-to-rear spacing buffer module; wherein the horizontal swing buffer module includes a main support 1, on which are arranged several groups of double-ear plates A8 which are rotatably connected to the front-to-rear spacing buffer modules one by one; as an example, a group of double-ear plates A8 are arranged at both ends and in the middle of the main support 1 (thereby a total of three groups of double-ear plates are arranged on the main support 1), and the three groups of double-ear plates A8 are located in the same horizontal plane and on the same side of the main support 1; wherein the middle double-ear plate A8 forms an angle of 90° with the length direction of the main support 1 (i.e., perpendicular to the main support 1), and the double-ear plates A8 at both ends form an angle of 60° with the length direction of the main support 1. The double-ear plates A8 and the main support 1 are mechanically processed, fixedly connected as a whole, and face the barge; the other side of the main support 1 faces the transport tugboat.
[0029] The two ear plates of the double ear plate A8 are arranged horizontally; a vertical through hole is opened at the same position of the two ear plates, and the double ear plate A8 is connected to one end of the front and rear spacing buffer module by vertically inserting a rotating connecting member (such as a pin 5) into the through hole.
[0030] The left and right sides of the two ear plates in the double ear plate A8 are provided with buffer blocks 2; the opposing surfaces of the two buffer blocks 2 are inclined surfaces that open outward, thereby the two buffer blocks 2 form a trumpet-shaped opening for buffering the impact when the transport tugboat sways left and right. The side of the buffer block 2 is provided with a threaded through hole, and is fixedly connected to the double ear plate A8 by the action of a fastener, thereby increasing the firmness between the buffer block 2 and the double ear plate A8, and improving the ability of the main bracket 1 to cope with the impact of horizontal swing.
[0031] The vertical bump buffer module includes a double ear plate B7 and a connecting ear plate 6. Several groups of the double ear plates B7 corresponding to the front and rear spacing buffer modules are connected to one side of the barge 9. As an example, three groups of the double ear plates B7 are connected to the front end of the barge 9 at the same spacing distance, toward the tail of the transport tugboat. The double ear plates B7 are processed separately and then fixed to the front end of the barge 9 with screws.
[0032] The two ear plates of the double-ear plate B7 are vertically parallel; a through hole is opened at the same position of the two ear plates, and a rotating connecting member (such as a pin 5) is horizontally inserted into the through hole, so that the double-ear plate B7 is rotatably connected with the connecting ear plate 6.
[0033] The upper and lower sides of the two ear plates in the double ear plate B7 are provided with buffer blocks 2; the opposing surfaces of the two buffer blocks 2 are inclined surfaces that open outward, thereby the two buffer blocks 2 form a trumpet-shaped opening for buffering the impact when the barge bumps up and down. The side of the buffer block 2 is provided with a threaded through hole, and is fixedly connected to the double ear plate B7 by the action of a fastener, thereby increasing the firmness between the buffer block 2 and the double ear plate B7, and improving the ability of the transposition to cope with the up and down bumps of the barge 9.
[0034] The connecting ear plate 6 is composed of a horizontal ear plate at one end and a vertical ear plate at the other end, wherein the vertical ear plate is a single ear plate, a through hole is provided in the center of the vertical ear plate, which is coaxial with the through hole of the double ear plate B7, and the vertical ear plate of the connecting ear plate 6 is rotatably connected to the double ear plate B7 through a rotating connection (such as a horizontally arranged pin 5); the horizontal ear plate of the connecting ear plate 6 is a double ear plate C10, which is rotatably connected to the other end of the two-way tube shock absorber 4 through a rotating connection (such as a vertically arranged pin 5).
[0035] The front and rear spacing buffer module includes several groups of two-way tube shock absorbers 4 that are rotatably connected to the connecting ear plates 6 one by one; as an example, the front and rear spacing buffer module includes three groups of two-way tube shock absorbers 4; one end of each group of the two-way tube shock absorbers 4 is connected to the stern of the transport tugboat through the double ear plate A8; the other end of each group of the two-way tube shock absorbers 4 is connected to the front end of the barge 9 through the connecting ear plate 6 and the double ear plate B7.
[0036] Both ends of the bidirectional cylinder shock absorber 4 are provided with a single ear plate 3. Specifically, the single ear plate 3 of the bidirectional cylinder shock absorber 4 close to the barge side is connected to the connecting ear plate 6 through a rotating connector (such as a pin 5); the single ear plate 3 close to the transport tugboat side is connected to the double ear plate A8 through a rotating connector (such as a pin 5), and the horizontal swing force generated by the single ear plate 3 is buffered by the buffer block 2 and the trumpet-shaped opening design formed by it, while assisting the shock absorbing function of the bidirectional cylinder shock absorber 4 itself, thereby achieving a double buffering effect.
[0037] Moreover, since the three sets of double-ear plates A8 are arranged on the main bracket 1, the middle double-ear plate A8 is 90° to the main bracket 1, and the double-ear plates A8 at both ends are 60° to the main bracket 1, so that the three sets of two-way cylinder shock absorbers 4 connected to the main bracket 1 have the characteristics of a right triangle and an equilateral triangle in terms of structure. Figure 1 The middle bidirectional cylinder shock absorber 4 (called: main spacing buffer device) forms a vertical structural relationship with the main support 1 in the length direction through the double ear plate A8, and is vertically fixed to the transport tugboat and barge, playing the role of main spacing buffer; the extended lines of the bidirectional cylinder shock absorbers 4 (called: auxiliary spacing buffer devices) on the left and right sides and the equilateral triangle structure formed by the main support 1 play the role of auxiliary spacing buffer.
[0038] When the transport tugboat in front suddenly turns, the main support 1 turns along with it, and the rear barge swings in the opposite direction under the action of inertia. The inner two-way cylinder shock absorber 4 is squeezed to provide support force, and the outer two-way cylinder shock absorber 4 is pulled back by tension. At the same time, when the two-way cylinder shock absorber 4 swings left and right, its single ear plate 3 squeezes the buffer blocks 2 on both sides of the double ear plate A8. The squeezed buffer blocks 2 have the function of providing buffering and auxiliary support, that is, the buffer blocks 2 and the double-line cylinder shock absorbers 4 on the left and right sides work together to provide horizontal swing buffering for the transport tugboat in front when it turns suddenly at high speed.
[0039] When the transport tugboat in front suddenly accelerates or decelerates, the three groups of opened two-way cylinder shock absorbers 4 stretch or contract under the action of the impact force to provide positive or reverse support; at the same time, since the middle two-way cylinder shock absorber 4 is in a vertical structural relationship with the main bracket 1 in the length direction and the two-way cylinder shock absorbers 4 on both sides are in an equilateral triangle structure with the main bracket 1 in the length direction, the connecting device can help disperse the vertical impact caused by sudden deceleration and avoid rigid collision.
[0040] During the operation of the transport tugboat towing the barge, when the front transport tugboat is subjected to vertical fluctuations caused by factors such as water flow and surge, the transport tugboat drives three sets of bidirectional cylinder shock absorbers 4 to bump up and down between the corresponding barge double-ear plates (specifically double-ear plates B7), squeezing the buffer blocks 2 on both sides of the double-ear plates B7 to alleviate the impact and avoid rigid collision. Since the double-ear plates B7 are installed at the same interval at the front end of the barge, combined with the buffer blocks 2 set on both sides thereof, the purpose of the connection device being able to provide uniform buffering is achieved, alleviating the problem of vertical and horizontal water flow impact force generated by the transport tugboat during the operation on the water.
[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
