Detailed Description
The invention is further illustrated in the following, in conjunction with the accompanying drawings and examples. In the following detailed description, exemplary embodiments of the invention are described by way of illustration only. It is needless to say that the person skilled in the art realizes that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive in scope.
As shown in fig. 1 to 11, the up-down two-way opening-closing type trailer compartment comprises a compartment floor 1 and baffle columns 11 fixedly arranged at four corners of the compartment floor 1, respectively, and four baffle columns 11 are known and are usually welded to the compartment floor 1.
A carriage baffle plate 2 is arranged between two adjacent baffle plate columns 11, at least the carriage baffle plate 2 at the front end of the carriage bottom plate 1 is a fixed baffle plate 21, and the front end of the carriage bottom plate 1 is a tractor position and does not need to be opened, so the front end is the fixed baffle plate 21.
At least one of the carriage baffles 2 at the two sides and the rear end of the carriage bottom plate 1 is a bidirectional opening and closing baffle 22, and when the bidirectional opening and closing baffle 22 is used for loading and unloading in this embodiment, the carriage baffles 2 can be opened upwards or downwards according to actual conditions. Most preferably, the two sides and the rear end of the carriage bottom plate 1 are provided with the two-way opening and closing baffles 22, so that three two-way opening and closing baffles 22 can be opened downwards according to the loading and unloading requirements of the packaged goods, and the two-way opening and closing baffles 22 can be opened upwards according to the direction when the bulk goods are unloaded, for example, when the bulk goods are unloaded from the left side, the left side can be opened upwards only by the two-way opening and closing baffles 22. It should be noted that the terms "front", "rear", "left" and "rear" in this embodiment are referred to as the directions of travel of the tractor when this embodiment is actually applied. Of course, according to the conventional dumping side, only one or two of the three carriage baffles 2 at the two sides and the rear end are designed as the bidirectional opening and closing baffles 22, and the carriage baffles 2 at the two sides and the rear end are designed to be only opened upwards, opened downwards or fixedly arranged, and the like, and the schemes are also in the protection range.
The bottom of the bidirectional opening and closing baffle 22 is provided with at least two lower pin connecting lugs 31 extending to the side surface of the carriage bottom plate 1, the side surface of the carriage bottom plate 1 is provided with lower pin hinge lugs 32 corresponding to the lower pin connecting lugs 31 respectively, and a lower hinge pin 33 is detachably arranged between the lower pin connecting lugs 31 and the corresponding lower pin hinge lugs 32. When the lower hinge pin 33 is installed, it may be used as a hinge pin for the bi-directional opening and closing plate 22 to be opened downwards, or fix the bi-directional opening and closing plate 22 together with a hinge structure at the upper part of the bi-directional opening and closing plate 22; when the two-way opening and closing baffle 22 is detached, the bottom of the two-way opening and closing baffle 22 can be fixed, so that the two-way opening and closing baffle 22 can be opened upwards conveniently.
Because the upward opening of the bi-directional opening and closing plate 22 according to this embodiment is mainly aimed at dumping of bulk cargoes, when the bulk cargoes such as coal, sand, stones and the like are transported, the bottom of the bi-directional opening and closing plate 22 is subjected to a much higher cargo pressure than the top, and the bottom of the bi-directional opening and closing plate 22 is obviously pressed outwards by the cargo pressure, so that the lower hinge pins 33 are blocked between the lower pin connection lugs 31 and the lower pin hinge lugs 32, and are not easy to take out. In order to solve the above problem, in this embodiment, a baffle bottom outward extrusion limiting device is disposed between the carriage bottom plate 1 and the bidirectional opening/closing baffle 22.
As shown in fig. 5, 7, 8 and 11, the baffle bottom external extrusion limiting device comprises an external extrusion limiting lug 34 fixedly arranged on the lower pin hinge lug 32 and extending to the bottom of the bidirectional opening and closing baffle 22, an external extrusion limiting gap 35 is arranged between the external extrusion limiting lug 34 and the bottom of the bidirectional opening and closing baffle 22, a hinge lug avoiding opening 36 corresponding to the external extrusion limiting lug 34 is arranged at the bottom of the bidirectional opening and closing baffle 22, and an external extrusion limiting pad 37 capable of being clamped to the external extrusion limiting gap 35 is rotatably arranged at the bottom of the bidirectional opening and closing baffle 22. When the outer extrusion limiting pad 37 rotates to the outer extrusion limiting gap 35, the outer extrusion limiting pad 37 takes the outer extrusion limiting lug 34 as a supporting point, and extrudes the bottom of the bidirectional opening and closing baffle 22 inwards, so that the outer extrusion effect of bulk goods on the bottom of the bidirectional opening and closing baffle 22 can be obviously reduced, and the lower hinge pin 33 has small clamping effect and can be conveniently taken out. When the bidirectional opening and closing baffle 22 needs to be opened, the outer extrusion limiting base plate 37 is rotated to be separated from the outer extrusion limiting gap 35, and the arrangement of the hinge lug avoiding opening 36 can avoid the obstruction of the outer extrusion limiting lug 34 to the opening and closing baffle 22.
The lower pin connecting lug 31 in this embodiment includes two lower pin connecting cylinders fixedly disposed at the bottom of the bidirectional opening and closing baffle 22 and located at the side of the carriage bottom plate 1, the lower pin connecting lug 32 includes a lower pin hinge plate fixedly disposed on the carriage bottom plate 1 and located between the two lower pin connecting cylinders, and the outer extrusion limiting lug 34 is integrally disposed on an outer extrusion supporting plate on the upper portion of the lower pin hinge plate, so that the lower pin hinge plate and the outer extrusion supporting plate can be processed at one time, thereby simplifying the structure and reducing the cost. The lower hinge pin 33 may be a conventional stepped pin, and the end without a step may be a split pin or a D-shaped pin.
The bottom of the bidirectional opening and closing baffle 22 is provided with a pad limiting protrusion 38 for preventing the outward extrusion limiting pad 37 from rotating downwards. When the outer extrusion limiting pad 37 is operated to be separated from the outer extrusion limiting gap 35, the outer extrusion limiting pad 37 is rotatably installed, so that the position of the outer extrusion limiting pad 37 separated from the outer extrusion limiting gap 35 is not easy to control, the outer extrusion limiting pad 37 can freely hang down due to dead weight under the conventional condition, and when the bidirectional opening and closing baffle 22 is opened downwards, the outer extrusion limiting pad 37 is particularly easy to interfere with the side face of the carriage bottom plate 1, so that the structure is damaged. The pad limiting protrusion 38 can limit the outer extruding limiting pad 37, so that the outer extruding limiting pad is not excessively and freely hung down to affect the downward opening of the bi-directional opening and closing baffle 22. The pad limiting protrusion 38 may be a bolt, a block, a rivet, or the like fixedly provided on the bi-directional opening/closing plate 22.
The structure of the above-mentioned baffle bottom external extrusion limiting device directly sets the external extrusion limiting lug 34 on the lower pin hinge lug 32, which belongs to the preferred scheme of simplifying the whole structure in this embodiment. In addition, the baffle bottom external extrusion limiting device can be arranged outside the lower pin hinge lug 32, and the schemes that the two-way opening and closing baffle 22 can be extruded against the bottom of the two-way opening and closing baffle 22 when limiting and the two-way opening and closing baffle 22 is released are not influenced are all within the protection range.
As shown in fig. 2, 3, 4 and 10, upper hinge pins 43 are respectively mounted on the upper parts of the two ends of the bi-directional opening and closing baffle 22 through upper pin sliding connection devices, and upper pin inserting cylinders 44 are respectively arranged on the baffle columns 11 at the two ends of the bi-directional opening and closing baffle 22. When the upper hinge pin 43 is inserted into the upper pin insertion cylinder 44, the upper hinge pin 43 may be used as a hinge pin for the bi-directional opening and closing barrier 22 to be opened upwards, or may form a fixation of the bi-directional opening and closing barrier 22 together with a hinge structure at the lower part of the bi-directional opening and closing barrier 22; when the upper hinge pin 43 is pulled out of the upper pin insertion cylinder 44, the fixing of the upper portion of the bi-directional opening/closing plate 22 can be released, and the bi-directional opening/closing plate 22 can be opened downward conveniently.
Whether the upper hinge pin 43 is inserted or pulled out, it is necessary to ensure that the upper hinge pin 43 does not slide axially at will, so as to ensure the stability of the bi-directional opening/closing plate 22 when it is opened upwards or downwards, and in this embodiment, a clutch locking device is disposed between the upper hinge pin 43 and the bi-directional opening/closing plate 22, so as to solve the above-mentioned problem.
The clutch locking device comprises an inserting limiting cylinder 41 fixedly arranged on the bidirectional opening and closing baffle 22, a spring propping cylinder 42 concentrically arranged is fixedly arranged on one side, away from an upper pin inserting cylinder 44, of the inserting limiting cylinder 41 on the bidirectional opening and closing baffle 22, an upper hinge pin 43 is arranged between the inserting limiting cylinder 41 and the spring propping cylinder 42, and the upper hinge pin 43 can be directly machined by adopting round steel. For the present embodiment, the insertion limiting cylinder 41 and the spring abutting cylinder 42 double as the upper pin sliding means. The upper hinge pin 43 is fixedly provided with an inserting limiting protrusion 45 between the inserting limiting cylinder 41 and the spring propping cylinder 42, the upper hinge pin 43 is sleeved with a locking spring 46 between the inserting limiting protrusion 45 and the spring propping cylinder 42, and the bidirectional opening and closing baffle 22 is provided with a separating limiting clamping groove 47 corresponding to the inserting limiting protrusion 45 between the inserting limiting cylinder 41 and the spring propping cylinder 42. The spring force of the locking spring 46 can enable the inserting limit projection 45 to lean against one end of the inserting limit cylinder 41, and the upper hinge pin 43 is inserted into the upper pin inserting cylinder 44 and forms stable connection; the upper hinge pin 43 is pulled out against the spring force of the locking spring 46, the insertion limiting protrusion 45 is clamped at the separation limiting clamping groove 47, and the upper hinge pin 43 is separated from the upper pin insertion cylinder 44 to form stable separation. The insertion limiting projection 45 of this embodiment is a round steel welded on the upper hinge pin 43, and the round steel can be designed longer and then used as a handle for operating the upper hinge pin 43. The present embodiment may use bolts, rivets, etc. fixedly disposed on the bi-directional opening/closing plate 22, and the head of the bolts, rivets, etc. is disposed away from the bi-directional opening/closing plate 22 by a distance greater than the distance from the axis of the upper hinge pin 43 to the bi-directional opening/closing plate 22 to form the separation limiting slot 47.
As shown in fig. 1, 6 and 9, the trailer body is generally longer in front and rear, and the two side two-way opening/closing flaps 22 are also longer, which simply depends on the two upper hinge pins 43 at the two ends, so that the strength requirement of opening the two-way opening/closing flaps 22 laterally cannot be easily met. Baffle sub-columns 12 are arranged between the baffle columns 11 on both sides of the carriage bottom plate 1 in the present embodiment, and the carriage baffle 2 on each side, that is, the bidirectional opening and closing baffle 22 on each side in the present embodiment, includes side sub-baffles 23 located between two adjacent baffle sub-columns 12 and between the baffle sub-columns 12 and the adjacent baffle columns 11. In this exemplary embodiment, the bidirectional opening and closing baffle 22 on each side is divided into a plurality of side sub-baffles 23, the upper hinge pins 43 are respectively arranged at the upper parts of the two ends of each side sub-baffle 23, so that the strength can meet the requirement, and of course, the corresponding upper pin inserting and closing cylinders 44 are also arranged on each baffle sub-column 12; to simplify the structure, two upper pin-inserting cylinders 44 are integrally provided on each of the shutter sub-columns 12. In addition, in this embodiment, at least two lower hinge pins 33 are arranged at the bottom of each side baffle plate 23, and this embodiment illustrates that three lower hinge pins 33 are arranged at the bottom of each side baffle plate 23.
