[0029] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] like Figure 1-Figure 5 As shown, the first embodiment of the utility model provides a trolley furnace sample hopper, a trolley furnace sample hopper, comprising a loading hopper 2 and a sealing mechanism, the loading hopper 2 has a receiving cavity for receiving a steel sample, the top of the loading hopper 2 has an opening, and the opening is connected to the receiving cavity;
[0031] The sealing mechanism is used to limit the steel samples stacked in the accommodating cavity to prevent the steel samples from rolling out of the accommodating cavity; the sealing mechanism includes a flap 3 and a locking hook, the flap 3 is an arc-shaped plate, and the flap 3 is arranged above the accommodating cavity, the loading bucket 2 has a first side and a second side opposite to each other, one end of the flap 3 is rotatably connected to the first side of the loading bucket 2, and the other end thereof is detachably connected to the second side of the loading bucket 2 through a locking hook; the flap 3 rotates around the connection between it and the loading bucket 2 in a first direction to expose the accommodating cavity, and the flap 3 rotates around the connection between it and the loading bucket 2 in a second direction to cover the accommodating cavity.
[0032] In this embodiment, due to the existence of the enclosure mechanism, as many round steel bar samples as possible can be stacked. After the round steel bar samples are stacked and placed in the accommodating cavity of the loading bucket 2, the stacking height exceeds the upper surface of the loading bucket 2, and then the flap 3 can be rotated in the second direction, so that the flap 3 covers the round steel bar samples, and then the second end of the flap 3 is locked by the locking hook. In this way, even if a large number of round steel bar samples are stacked, the round steel bar samples will not roll down when the trolley furnace sample hopper is transported, thereby increasing the loading capacity of the trolley furnace sample hopper to a certain extent, avoiding accidents of injury due to the collapse of round steel bar samples, and improving its safety.
[0033] The first direction is counterclockwise, and the second direction is clockwise.
[0034] As a preferred embodiment, Figure 2 As shown, the loading bucket 2 is in the shape of a rectangular box, the left end of the flap 3 is rotatably connected to the upper surface of the left side of the loading bucket 2, and the right end of the flap 3 is detachably connected to the outer wall of the right side of the loading bucket 2 via a locking member. Figure 3 and Figure 4 As shown, a pin seat 203 is installed on the upper surface of the left side of the loading bucket 2, and a pin 303 is installed on the left end of the flap 3, and the pin 303 is rotatably connected to the pin seat 203. It should be noted that the round steel bar sample loaded in the loading bucket 2 at this time is a short sample, and its length is less than the width of the loading bucket 2, that is, when the short sample is placed, the length direction of the short sample is perpendicular to the length direction of the loading bucket 2.
[0035] At this time, the flap 3 rotates counterclockwise to expose the accommodating cavity in the loading bucket 2, and when the flap 3 rotates clockwise, the flap 3 covers the accommodating cavity.
[0036] It should be noted that, since the round steel bar samples are cylindrical and easy to roll, they can be stacked freely in the accommodating cavity, but the portion beyond the accommodating cavity cannot be stacked in a square shape, and the round steel bar samples in this portion can only be stacked in a semicircular shape. Therefore, the flap 3 in this embodiment has an arc shape in order to better fit the round steel bar beyond the accommodating cavity.
[0037] As an optional embodiment, the loading bucket 2 is in the shape of a rectangular box, one end of the flap 3 is rotatably connected to the top of the front of the loading bucket 2, and the other end is detachably connected to the back of the loading bucket 2 through a locking member. This type of trolley furnace sample hopper is used to load long-sized round steel bar samples, that is, when the round steel bar samples are stacked in the loading bucket 2, the length direction of the round steel bar samples is perpendicular to the width direction of the loading bucket 2. Moreover, the flap 3 is also connected to the loading bucket 2. Figure 2 The appearance of the flap 3 in the embodiment is different, specifically, Figure 5 As shown, the cross section of the flap 3 in the length direction is arc-shaped, and Figure 2 The cross section of the flap 3 in the width direction is arc-shaped. That is, the flap 3 in the previous embodiment rotates around the upper surface of the left side of the loading bucket 2, while the flap 3 in this embodiment rotates around the top of the front side of the loading bucket 2, and the installation directions of the two are different.
[0038] Preferably, Figure 2 and Figure 3 As shown, the enclosing mechanism also includes two baffles 4, one baffle 4 is installed on the front side of the loading bucket 2 near the top, and the other baffle 4 is installed on the back side of the loading bucket 2 near the top, and the two baffles 4 are symmetrical about the flap 3. Furthermore, the upper surface of the baffle 4 is an arc-shaped surface, and the arc-shaped surface of the baffle 4 is slightly lower than the inner surface of the flap 3. It should be noted that when transporting the sample hopper of the trolley furnace, the sample hopper of the trolley furnace may be hit or severely bumped. In order to prevent the round steel bars from falling from the front or back of the flap 3, two flaps 3 are installed, so that the flap 3 can block the stacked round steel bars and prevent the round steel bar samples from falling from the front or back of the flap 3.
[0039] Preferably, Figure 2 , Figure 3 and Figure 4As shown, the lock hook comprises a spring hook 301, a fixed plate 202 and a hanging ring 5, wherein two spring hooks 301 are provided, the top ends of the two spring hooks 301 are installed at the right end of the flap 3, two vertically arranged fixed plates 202 are installed on the right side of the loading bucket 2, and multiple hanging rings 5 are sequentially installed on each fixed plate 202 along its height direction. After the round steel bar samples are stacked, the loading bucket 2 can be rotated clockwise to limit the stacked round steel bar samples, and then the spring hook 301 at the right end of the flap 3 is hooked to a suitable hanging ring 5. It should be noted that since the height of the stacked round steel bar samples will deviate each time, if only one hanging ring 5 is installed, the flap 3 may not be covered. In this embodiment, there are multiple hanging rings 5, and they are sequentially arranged along the height direction of the fixed plate 202, so that the spring hook 301 can be reasonably selected to be hung on the hanging ring 5 of the appropriate height, avoiding the phenomenon that the flap 3 cannot be covered due to the deviation of the stacking height.
[0040] Preferably, Figure 2 As shown, three bottom plates 201 are installed at the bottom of the loading bucket 2. The three bottom plates 201 are arranged in sequence along the length direction of the loading bucket 2. The length direction of the bottom plates 201 is perpendicular to the length direction of the loading bucket 2. A slot for forklift teeth to be inserted is formed between two adjacent bottom plates 201. It should be noted that the conventional hopper 1 is Figure 1 As shown, two handle slots 101 are respectively provided on both sides of the hopper 1. This type of hopper 1 can only be carried manually, which has low carrying efficiency and cannot be used with a forklift. However, the loading hopper 2 in this embodiment can be used with a forklift, and the two teeth of the forklift can be inserted into the two slots to lift the loading hopper 2.
[0041] Preferably, Figure 2 As shown, the side wall and the inner bottom wall of the loading bucket 2 are provided with a plurality of heat conducting holes, the flap 3 is provided with a plurality of through holes 302, and the baffle 4 is provided with a plurality of holes 401. It should be noted that Figure 1 The hopper 1 shown in the figure can only be used to load round steel bar samples, but cannot be directly placed in the trolley furnace. This is due to the following two reasons. First, there are no heat conduction holes on the hopper 1, and the round steel bars loaded in the hopper 1 cannot be fully heated. Second, the round steel bars stacked in the hopper 1 are prone to collapse.
[0042] The trolley furnace sample hopper in this embodiment has holes on the loading hopper 2, the flap 3 and the baffle 4, so there is no obstruction to the heating of the round steel bars loaded therein, ensuring that the round steel bars can be fully heated. In addition, due to the existence of the sealing mechanism, the stacked round steel bars can also be limited to prevent them from collapsing.
[0043] Embodiment 2:
[0044] A trolley furnace has a uniform temperature zone in the trolley furnace, and a plurality of trolley furnace sample hoppers of the first embodiment are arranged in the uniform temperature zone, and the size of the trolley furnace sample hopper is not larger than the size of the uniform temperature zone. The trolley furnace sample hopper is used to place round steel bar samples to be annealed.
[0045] It should be noted that in the conventional trolley furnace, multiple bases for placing steel samples are arranged in the uniform temperature zone, and the bases are formed into rectangular plates. However, when placing round steel bar samples, due to the lack of an effective limiting mechanism, the round steel bar samples stacked there are at risk of collapse.
[0046] Figure 1 Although the existing hopper 1 shown in the figure can be placed on the base of the trolley furnace to replace the base, which can avoid the risk of collapse of the round steel bar sample to a certain extent, this type of hopper 1 lacks heat conduction holes, and the round steel bars loaded in the hopper 1 cannot be fully heated. Moreover, when a large number of round steel bars are stacked, they are prone to collapse.
[0047] Since the trolley furnace sample hopper in the first embodiment is installed in the present trolley furnace, the heating of the round steel bars loaded therein will not be hindered, thereby ensuring that the round steel bars can be fully heated and the stacked round steel bars can be limited to prevent them from collapsing.
[0048] Optionally, the bottoms of multiple trolley furnace sample hoppers are welded within the uniform temperature zone of the trolley furnace.
[0049] In the description of the present invention, it should be noted that the terms "upper" and "lower" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0050] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the insides of two components.
